FAG K387-A-382-S belongs to tapered roller bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for K387-A-382-S and any equivalents.

The FAG tapered roller bearing K387-A-382-S is built to handle radial and axial loads in one direction. Its tapered rollers and raceways make linear contact, which spreads the load and gives it high capacity. You will find it in gearboxes, wheel axles, and industrial machinery where combined forces are present. MR Industrial Accessories LLC supplies this bearing and can help you confirm the right part number for your application.

The part number K387-A-382-S follows the K…-A-…-S pattern. The leading K means it is a single-row tapered roller bearing with a separable cone and cup. The A in the middle typically denotes a contact angle or an internal design variant. The S suffix can point to a surface treatment or a special tolerance. In K387-A-382-S, the numbers correspond to the standardized dimensions of the cone and cup. If you need to decode a specific code, send it to our team by WhatsApp or email.

Tapered roller bearings are common in automotive, metalworking, mining, and agricultural equipment. They show up in transmission cases, speed reducers, machine tool spindles, conveyor rollers, and earthmoving machinery, as well as in railway and construction applications. Because they take combined loads, they suit shafts that see radial and axial forces at the same time, especially where rigidity and precision matter.

When selecting a tapered roller bearing, consider radial and axial load, rotational speed, and the operating environment. Check sealing: in dusty or wet conditions, add separate seals. Mounting requires precise alignment between cone and cup, as these bearings are not self-aligning. Lubrication can be grease or oil depending on the application, and internal clearance must be set carefully. Too much clearance causes vibration; too little raises temperature. Our team can walk you through these points.

Tapered roller bearings are made to international standards, so part numbers can often be interchanged between manufacturers when the main dimensions and contact angle match. However, suffixes are not always equivalent: the same basic number may differ in tolerance, treatment, or cage. When looking for a replacement, compare the full designation, not just the numeric portion. Send us the complete part number and we will help you identify the right option.
