Description
SKF RLYE 204 A is a y-bearing (insert bearing) reference, within Bearings. Request a quote for RLYE 204 A via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF RLYE A series Y-bearing is an insert with an extended inner ring and set screw locking system, designed to be mounted in split or pillow block housings. It is used in equipment where the shaft rotates at moderate speeds and loads are mainly radial, such as conveyor belts, fans and mixers. MR Accesorios Industriales supplies this line as an official brand and helps you choose the correct part number for your application.
The RLYE A series designation reads as follows: the letters RLYE identify a Y-bearing with extended inner ring and set screw locking; the final letter A indicates a construction variant within the family. The three-digit number in the middle, as in RLYE 204 A or RLYE 206 A, encodes the bore diameter and main dimensions. To order the replacement, provide the full part number exactly as shown on the nameplate or equipment drawing.
These inserts are mounted in split, pillow block or flanged housings, and are common in belt conveyors, bucket elevators, mills, mixers and industrial fans. In Argentina they are found in food plants, cement plants, tanneries and aggregate processing plants, where maintenance is done with the equipment stopped and quick interchangeability is a priority. They are also used on low-speed transmission shafts that require simple and robust support.
To select the right Y-bearing, consider the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. If there is dust or moisture, effective sealing is advisable; if the shaft is prone to deflection, check the internal clearance. During mounting, clean the shaft seat, apply the recommended torque to the set screws and lubricate according to the operating regime. Careful alignment of the housing prevents parasitic stresses and extends service life.
Regarding equivalences, Y-bearings are interchangeable between manufacturers if dimensions, locking system and sealing match. A similar part number is not enough: you must compare bore diameter, overall width, locking type and location of lubrication holes. If in doubt, send us a photo of the part and the shaft dimensions, and we will confirm the available alternative at MR Accesorios Industriales.
To request a quote for the SKF RLYE A series Y-bearing, write to us on WhatsApp with the full part number (for example, RLYE 204 A or RLYE 206 A) and the quantity you need. If you do not have it at hand, send us the shaft and housing dimensions and we will identify it together. Our technical team with more than 80 years of experience in industrial distribution will respond with the option that best suits your equipment.

Frequently Asked Questions
- How do I identify the correct part number for an RLYE A Y-bearing?
- Look for the part number engraved on the outer ring or on the housing nameplate. The RLYE A series includes a number that defines the bore diameter; for example, RLYE 204 A and RLYE 206 A correspond to different shaft sizes. If you cannot find it, measure the shaft with a caliper and send us the data.
- What is the difference between a Y-bearing and a deep groove ball bearing?
- The Y-bearing has an extended inner ring and a shaft locking system, usually set screws, which allows direct mounting on shafts without a shoulder. The standard deep groove ball bearing requires interference fit or an adapter sleeve. The Y-bearing is used in split housings and applications with simple maintenance.
- How often should a Y-bearing be lubricated in continuous service?
- The frequency depends on speed, load and environment. Under normal conditions, it is recommended to check lubrication every 2000 operating hours or at each scheduled stop. If there is dust, moisture or high temperatures, shorten the interval. Use the grease recommended by the equipment manufacturer and do not mix different bases.
