INA NUTR 35-A Track Roller Bearing 35x72x29 mm | Yoke Type Track Roller

What is the INA NUTR 35-A Track Roller?

The INA NUTR 35-A is a premium yoke type track roller bearing designed to run directly on tracks, guide rails and cam profiles in demanding industrial applications.

The bearing incorporates a full complement of cylindrical rollers, allowing it to carry exceptionally high radial loads without the use of a cage. This design maximizes load capacity and provides excellent resistance to shock loads, making the NUTR series ideal for continuous-duty industrial machinery.

The bearing is equipped with a thick-walled outer ring, an inner ring, axial guidance and double labyrinth seals, providing reliable protection against dust, dirt and moisture while maintaining long service life.

Manufactured by INA, a brand of the Schaeffler Group, the NUTR 35-A meets OEM-quality standards for demanding industrial applications.

FAQ

What are the bearing dimensions?

The bearing dimensions are 35 × 72 × 29 mm.

What is a yoke type track roller?

It is a bearing specifically designed to run on tracks, guide rails and cam profiles while carrying high radial loads.

Does the bearing have seals?

Yes. It features double labyrinth seals that protect against contamination and retain lubricant.

Does it contain a cage?

No. The NUTR series uses full complement cylindrical rollers, allowing significantly higher load capacity.

What is the limiting speed?

The limiting speed is 2,100 rpm under grease lubrication.

Frequently Asked Questions from Mechanics and Engineers

Why does a full complement bearing carry higher loads?

Because eliminating the cage allows more cylindrical rollers to fit inside the bearing, increasing the contact area and overall radial load capacity.

What is the purpose of labyrinth seals?

Labyrinth seals prevent dust, dirt and moisture from entering the bearing while minimizing lubricant loss.

What are the most common causes of track roller failure?

• Misaligned guide rails
• Excessive loading
• Inadequate lubrication
• Contamination
• Raceway damage
• Improper installation
