Models we quote fast

RA106RRB

RA106RRB agricultural insert bearing, 1-3/8 in bore, spherical OD.

Wide inner-ring insert bearing with eccentric locking collar, molded shroud seals, spherical outside diameter for self-aligning housings. Typically factory-greased and non-relubricatable.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-3/8 in (34.93 mm). OD 72 mm (2.835 in), spherical. Inner ring width about 1.00 in; overall width with collar about 1.53 in.
Typical use: Housed shafts on tillage implements and farm machinery where the housing bore is spherical.
Interchange: Commonly crossed to RA106NPPB / GRA106RRB families; field numbers often include John Deere JD9336 and JD9462. Confirm stamp and housing.

Buyers in Mongolia and Russia request RA106RRB when replacing a 1-3/8 in insert in a self-aligning housing. The spherical OD lets the insert seat in a matching spherical housing and take initial misalignment on implement frames. Send quantity, destination port, and whether the collar is required.

RA106RR

RA106RR insert bearing, 1-3/8 in bore, cylindrical OD.

Same RA-RR family and 1-3/8 in shaft size as RA106RRB, but cylindrical outside diameter for straight housing bores. Eccentric collar, double sealed, typically non-relubricatable.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-3/8 in (34.93 mm). OD 72 mm (2.835 in), cylindrical. Inner ring width about 1.00 in.
Typical use: Implement shafts in housings that take a straight (cylindrical) insert OD — not a spherical seat.
Interchange: Not a drop-in for RA106RRB if the housing seat is spherical. Check OD form before ordering.

RA106RR is the cylindrical-OD counterpart of RA106RRB. Importers often mix the two suffixes. Quote the housing type or send a photo of the old outer ring.

CF5002-ASSY

CF5002-ASSY pickup cam-follower assembly for agricultural headers.

Complete pickup cam-follower assembly (PEER-style CF5002 family), quoted as a unit, not a loose ring only.

Typical interchange size — confirm on TIMKEN drawing.: Sold as a complete assembly. Ask for the sample or OEM code if the housing differs.
Typical use: Combine and header pickup reels.
Interchange: Crossed in the trade as PEER CF5002-ASSY / CF5002NYY8 class pickup cam followers. Confirm the full assembly, not a single bearing.

Header shops in CIS markets order CF5002-ASSY when the pickup reel cam follower is worn as a set. Send a photo of the old assembly if the stamp is gone.

RA103RRB2

RA103RRB2 insert bearing, 1-1/4 in bore, spherical OD.

Wide inner-ring insert, eccentric collar, spherical OD, double sealed. The “2” suffix is the 1-1/4 in bore variant — not the 1-3/16 in RA103RRB.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-1/4 in (31.75 mm). OD 62 mm (2.441 in), spherical. Overall width about 1.41 in.
Typical use: Implement housed shafts on 1-1/4 in round shafts.
Interchange: Often listed against Fafnir RA103RRB2; OEM stamps include Case-IH 156011C91 / 156011C92 class numbers. Verify 1-1/4 in, not 1-3/16 in.

RA103RRB2 is a frequent spare for 1-1/4 in implement shafts. If the old part says RA103RRB without “2”, measure the shaft before ordering.

GRA115RRB

GRA115RRB relubricatable insert bearing, 1-15/16 in bore, spherical OD.

GRA-RRB series insert: eccentric collar, spherical OD, double sealed, with a grease provision. Use this when the machine is maintained with periodic relubrication.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-15/16 in (49.21 mm). OD 90 mm (3.543 in), spherical. Inner ring width about 1.188 in.
Typical use: Larger implement shafts and housed units that need a 1-15/16 in insert.
Interchange: Not the 2 in GRA115RRB2. GRA means relubricatable; RA115RRB would be the sealed-for-life cousin. Confirm grease hole and shaft size.

Distributors covering Russian and Mongolian fleets use GRA115RRB on larger shafts when the housing allows regreasing. State if you need the collar (often ordered as GRA115RRB+COL).

RA100RRB

RA100RRB insert bearing, 1 in bore, 52 mm spherical OD.

Compact RA-RRB insert, eccentric locking collar, spherical OD, molded shroud seals, typically non-relubricatable.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1 in (25.4 mm). OD 52 mm (2.047 in), spherical. Inner ring width about 0.844 in.
Typical use: Smaller housed shafts on agricultural implements.
Interchange: Standard Fafnir/Timken RA100RRB class. Confirm spherical housing seat.

RA100RRB is the 1 in entry size in this insert family. Useful for mixed-container orders with the 1-3/8 in and 1-3/4 in RA parts.

GW210PP4

GW210PP4 disc harrow bearing, 1-1/8 in square bore, 90 mm OD.

Heavy-duty disc-harrow bearing with 1-1/8 in square bore, cylindrical OD, triple-lip style seals. Commonly relubricatable in this GW210PP4 designation.

Typical interchange size — confirm on TIMKEN drawing.: Square bore 1-1/8 in (28.58 mm). OD 90 mm (3.543 in), cylindrical / flat OD. Width about 1.188 in inner and outer.
Typical use: Disc harrow gangs on square shafts, including AMCO-style discs and similar tillage tools used in dry and abrasive soils.
Interchange: Often crossed to BCA DC210TTR4, NTN 7AS10-1-1/8D1, AMCO G10446 / G11078. Do not confuse with GW210PPB4 (spherical OD variant).

Square-bore gang bearings are a core request from disc-harrow repair shops. GW210PP4 fits 1-1/8 in square shafts with a straight 90 mm OD. Ask if the old part has a grease fitting.

W209PPB2

W209PPB2 disc harrow bearing, 45 mm round bore, 85 mm OD.

Round-bore agricultural disc bearing with heavy contact / triple-lip style seals and spherical or farm-implement OD as supplied. Built for mud, wrap, and grit.

Typical interchange size — confirm on TIMKEN drawing.: Bore 45 mm / 1.772 in, round. OD 85 mm (3.347 in). Width about 30.18 mm / 1.188 in.
Typical use: Disc harrows and other tillage tools on round shafts in wet or abrasive fields.
Interchange: Commonly listed with DS209TT2 / R3-209E3 class numbers. Confirm round bore, not hex or square.

W209PPB2 is quoted next to square-bore GW210PP4 so a buyer can cover both shaft styles on one packing list.

RA107RR

RA107RR insert bearing, 1-7/16 in bore, cylindrical OD.

RA-RR insert, eccentric collar, cylindrical OD, double sealed, typically non-relubricatable.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-7/16 in (36.51 mm). OD 72 mm (2.835 in), cylindrical. Inner ring width about 1.00 in.
Typical use: Implement shafts that need 1-7/16 in rather than 1-3/8 in (RA106) in a straight housing bore.
Interchange: Same 72 mm OD family as RA106RR, different bore. Measure the shaft; 1/16 in is enough to seize or slop.

RA107RR sits between RA106 and RA108 sizes. CIS workshops often order it after measuring a worn 1-7/16 in shaft.

209KRRB2

209KRRB2 hex-bore agricultural bearing, 1-1/2 in hex, 85 mm OD.

Special ag bearing with 1-1/2 in hexagonal bore, spherical OD, sealed and pre-lubricated for hex shafts.

Typical interchange size — confirm on TIMKEN drawing.: Hex bore 1-1/2 in. OD about 85 mm / 3.35 in, spherical. Inner ring width about 1.18 in; outer ring width about 0.75 in.
Typical use: Hex-shaft farm equipment, including baler applications associated with John Deere AE40895.
Interchange: Also seen as Fafnir 209KRRB2, BCA HPS108GPH, Link-Belt 24K209N. Confirm hex size across flats.

209KRRB2 is the hex-bore counterpart to the round and square disc bearings on this page. Buyers replacing AE40895 should send the hex measurement.

RA112RRB

RA112RRB insert bearing, 1-3/4 in bore, 85 mm spherical OD.

RA-RRB insert, eccentric collar, spherical OD, double sealed, typically non-relubricatable.

Typical interchange size — confirm on TIMKEN drawing.: Bore 1-3/4 in (44.45 mm). OD 85 mm (3.347 in), spherical. Inner ring width about 1.188 in.
Typical use: Larger implement shafts in self-aligning housings.
Interchange: Field crosses include John Deere AE12601 / JD8578 and Case-IH FH05041 class numbers. Confirm collar if the old unit was sold as +COL.

RA112RRB is the 1-3/4 in size most export buyers pair with RA106RRB in the same crate.

207KYY

207KYY agricultural ball bearing, 35 mm round bore, 72 mm OD.

Round-bore agricultural / 200-series ball bearing with KYY-style dual seals. Not a hex-bore KRRB disc bearing.

Typical interchange size — confirm on TIMKEN drawing.: Bore 35 mm (1.378 in), round. OD 72 mm (2.835 in). Width about 25 mm (0.98 in).
Typical use: Farm implements and related shafts that take a metric 35 mm 207-size sealed bearing.
Interchange: Listed as Fafnir 207KYY class; do not substitute 207KRRB9 (1-1/8 in hex) without checking the shaft.

207KYY is a metric round-bore spare. If the customer says “207 hex harrow bearing”, they likely want a KRRB number instead — ask for a photo.

Need a nearby size or a housing unit? Send the OEM number or a photo of the old bearing.
