Description

The INA K-TV series is a line of cylindrical roller thrust bearings built to carry heavy axial forces in one direction. A glass-fiber reinforced polyamide cage holds the cylindrical rollers in place, which supports accurate running where thrust is the main load. Typical installations include industrial machinery, transmission equipment and assemblies that call for high axial capacity and stiffness.
Reading the designation helps when you order. The K marks a cylindrical roller thrust bearing with a cage; TV identifies a polyamide cage reinforced with glass fiber, suited to higher speeds and moderate temperatures. Numbers such as K81102-TV, K81103-TV and K81104-TV step through the size range, and each code matches one set of dimensions. Confirm the exact code before requesting a quote.
These bearings appear in gearboxes, machine tool spindles, positive displacement pumps, cranes and lifting equipment, as well as overhead cranes, presses and power transmission systems with significant axial thrust. Because they take load in a single direction, they are usually paired with a radial bearing that handles radial forces.
Selection depends on the size and direction of the axial load, the speed and the operating environment. The support surfaces must be parallel and rigid, since the bearing does not compensate for angular misalignment. Use oil or high-viscosity grease according to speed and temperature, check axial clearance, and make sure the support washers, often supplied separately, are properly secured. Stay within the temperature limits for the TV cage.
When replacing a bearing, compare dimensions and operating conditions, not just the code; cylindrical roller thrust bearings from different brands can differ in size and load capacity. MR Industrial Accessories can advise on compatibility with other brands when full technical data is available. Do not assume equivalences without checking the specifications.

Frequently asked questions
- What does the TV suffix mean in the K-TV designation?
- TV indicates a polyamide cage reinforced with glass fiber. It is light and resistant, suitable for high speeds and moderate temperatures. It does not alter the outer dimensions, but it affects dynamic behavior.
- How do I choose the correct code from the K-TV series?
- The number after K gives the bearing size. You need the housing dimensions and the axial load to be carried. If the code is unknown, send the measurements or the equipment part number and we will help identify it.
- Does this bearing support radial loads?
- No. Cylindrical roller thrust bearings are made for predominantly axial loads in one direction. Radial loads require complementary radial bearings. Respecting this condition helps avoid premature failure.
