The INA Y-bearing series SK KTT L is an insert with a spherical outer ring, designed to mount in split or flanged housings and handle light drives with commercially toleranced shafts. Its sealed design and set screw locking system allow compact units to be assembled in continuously operating equipment. MR Accesorios Industriales carries this line as an official brand, with technical advice to choose the correct variant according to the shaft and housing.
The designation of these inserts is read in blocks. The letters SK identify the Y-bearing series with spherical outer ring and set screw locking. The number that follows — as in SK112-312-KTT-L402/70 — refers to the shaft diameter and the design variant. The KTT suffix indicates the sealing type: contact seals that protect against dust and moisture. The final letter L indicates a particular execution within the series, and the following numbers complete the mounting definition. To request a quote, send us the complete part number as it appears on the equipment.
These Y-bearings are used in belt conveyors, packaging belts, bucket elevators, mixers and industrial fans. In the Argentine market they appear in food plants, meatpacking plants, flour mills, aggregate processing plants and packaging lines. They are also common in material handling equipment and agricultural machinery. Their insert format simplifies replacement: they mount in standard split or flanged housings, which reduces downtime when a complete unit must be replaced.
To select the correct insert, take into account the shaft diameter, the housing type and the environmental conditions. The KTT sealing is advisable in dusty or humid environments; if there are frequent washdowns, verify the additional protection. Set screw locking requires tightening to the recommended torque and on a shaft with adequate tolerance. Factory lubrication is usually sufficient for the service life, but in severe applications it may require replenishment. Housing alignment and internal clearance are key to avoiding parasitic loads and premature failures.
As for equivalents, Y-bearings are interchanged between manufacturers by shaft diameter, width and locking type, but not all suffixes match. An insert with contact sealing does not replace one with simple sealing without verifying the required protection. The INA, FAG and other European brand series usually share basic dimensions, although the locking system and sealing may vary. It is always advisable to validate the complete part number and the working conditions before substituting a unit.

- You need the shaft diameter, the housing type and the working conditions. With the complete insert part number or a photo of the identification tag we can confirm the exact variant and quote it.
- Is this insert compatible with housings from other brands?
- In general, Y-bearings are interchanged by shaft and width dimensions, but the locking and sealing system may vary between manufacturers. Always verify the dimensions and the locking type before replacing.
