The INA SK KTT series covers Y-bearings, also known as insert bearings: ball bearings with a spherical outer ring and a shaft locking mechanism that mounts directly onto unground shafts. They suit transmission and conveying systems that call for a compact, sealed, easy-to-install unit. MR Industrial Accessories supplies this line to industrial customers across the United States and several Latin American countries.

The part number breaks down into segments. SK marks the insert bearing family with a spherical outer ring. KTT specifies the seal design, which uses lips to hold grease in and keep contaminants out. L denotes a construction or lubrication variant, and AH identifies the shaft locking method. A full reference like SK104-208-KTT-L402/70-AH10 stacks the size code, KTT seal, L variant and AH mounting. For a quote, send the number exactly as it appears on the equipment.

Typical installations include split plummer block housings, take-up frames and conveyor roller units. You will find them on belt conveyors, grain elevators, mills, feed plants, handling yards and packaging lines, as well as irrigation systems, industrial ventilation and agricultural machinery. They work well when the shaft is neither hardened nor ground and a straightforward, repeatable mounting is needed.

When choosing an insert bearing, confirm the shaft diameter and the locking style the housing accepts. The KTT seal handles dusty, damp or frequently washed-down areas; for elevated temperatures or high axial loads, check the appropriate L variant. During installation, seat the bearing without hitting the seal lips, tighten the shaft lock per the AH system and verify housing alignment. Relubricate only if the bearing is designed for it, and keep the seal area clean.

Y-bearings come from multiple manufacturers, each with its own naming system. Interchangeability hinges on principal dimensions, locking method and seal type, not just the part number. Before swapping one insert bearing for another, compare shaft diameter, overall width, locking hole positions and locking system. If anything is unclear, send the original part number and shaft dimensions; MR Industrial Accessories can help you identify the correct equivalent.
