FYCJ-35

Needle Roller Bearing

Product Features

Slim, elongated needle rollers replace standard rollers, giving a large number of rollers and long contact lines — an extremely thin radial cross-section carries substantial radial load in limited installation space
Available with or without an inner ring (running directly on a hardened shaft), with or without a cage (full-complement), and as cam followers integrating the outer raceway with a mounting stud
Commonly used in transmissions, automotive/motorcycle engines, gearboxes, and cam-follower/linkage mechanisms in machine tools and automation equipment
This series includes many part numbers, some from specialized catalogs — Nahshon, NSK's distributor in Taiwan, welcomes inquiries with the part number for factory spec and quote confirmation

Product Description

This category covers NSK needle roller bearings. Needle roller bearings use slim, elongated rollers instead of standard rollers, giving a large number of rollers and long contact lines — this allows an extremely thin radial cross-section to carry substantial radial load within limited installation space, making them more compact than standard ball or roller bearings of the same outer diameter. Available with or without an inner ring (running directly on a hardened shaft raceway), with or without a cage (full-complement), and as cam followers integrating the outer raceway with a mounting stud. Commonly used in transmissions, automotive/motorcycle engines, gearboxes, and cam-follower/linkage mechanisms in machine tools and automation equipment.

This category includes many part numbers, some of which require NSK's specialized catalog for full spec confirmation. Nahshon, NSK's distributor in Taiwan, welcomes inquiries with the part number — we will confirm the current code, spec and quote with the factory; sourcing support is also available for discontinued models.

FAQ

What's the difference between the Z, ZZ and DDU suffixes?

Z means a single-side steel shield, ZZ means steel shields on both sides, and DDU means contact rubber seals on both sides. Shields suit general environments and high speeds; rubber seals give better dust and water protection with slightly higher friction torque — choose based on your dust exposure and lubrication method.

When should I choose C3 clearance instead of standard clearance?

For motors or other applications with noticeable temperature rise, or high-speed operation, the inner ring expands from heat and reduces the clearance — choose C3 in that case. Standard clearance is fine for general room-temperature, low-speed use. See Nahshon's technical resources for a clearance selection guide.

Is FYCJ-35 in stock in Taiwan? What is the lead time?
