NUPK310NR Single Row Cylindrical Roller Transmission Bearing for Toyota

The NUPK310NR from DUHUI Bearing is a single-row cylindrical roller bearing for Toyota transmission applications. It has a 50.00 mm bore, 110.00 mm outside diameter, 27.00 mm width, a 1:12 tapered bore, and an outer-ring snap ring. Public product data identifies FBJ NUPK310NR and links this bearing family to NTN/SNR NUPK310HTNRSUV8 and the earlier NUPK310NRV4 reference.

Application note: Toyota fitment is confirmed at the brand level. Verify the vehicle model, production year, transmission configuration, shaft location, and original bearing number before ordering.

Product Features

• Single-row cylindrical roller design. The bearing geometry supports radial loading in a transmission shaft assembly.
• 50 x 110 x 27 mm envelope. The key dimensions support precise comparison with the original transmission bearing and housing.
• 1:12 tapered bore. The tapered bore requires direct confirmation of the shaft interface before installation.
• NR retaining feature. The outer-ring groove and snap ring provide an axial locating feature when the matched housing configuration requires it.
• Cross-reference support. FBJ NUPK310NR and NTN/SNR NUPK310HTNRSUV8 references assist part identification during replacement.

Installation Notes

• Confirm the transmission application. This is a standard cylindrical roller bearing, not a wheel bearing. Match the original part number, shaft position, and dimensions before installation.
• Inspect the tapered shaft seat. Check the shaft taper, seating surface, and contact pattern before fitting the bearing.
• Check the snap ring location. Confirm that the housing has the correct groove and axial location for the NR retaining arrangement.
• Apply force to the correct ring. Use an approved installation method and do not transmit mounting force through the rollers.
• Follow the transmission service procedure. Use the applicable service procedure for assembly order, lubrication, axial clearance, and retaining components.
