Product Overview
NSK 3304BTNG YRLN5 is a double-row angular contact ball-bearing designation. This design is typically selected where combined radial and axial loads must be handled in a compact bearing position.
Bearing replacement is more than matching the bore, outside diameter and width. Internal clearance, cage design, sealing, pairing, fits, lubrication, load direction and speed can all affect whether a similar-looking bearing is suitable in service.
MAVORIX can coordinate exact-model sourcing, supplier comparison and document requests in China. Final bearing approval should remain with the buyer's engineer or qualified maintenance team.

Compatibility and Selection Notice
Check the complete YRLN5 suffix and the axial-load arrangement. A double-row angular contact bearing is not automatically interchangeable with two separate single-row bearings.
Confirm the complete suffix, old bearing marking, machine position, dimensions, load, speed, temperature, lubrication and mounting arrangement before releasing an order.

MAVORIX Bearing Sourcing Support
MAVORIX is an independent China-side sourcing and supplier coordination partner, not the bearing manufacturer or an authorized distributor. We can help organize mixed bearing lists, compare complete designations, request supplier documents, coordinate label and dimension checks, and consolidate MRO shipments.
For a replacement inquiry, send the full suffix rather than only the basic bearing number. Related support is available through our industrial sourcing, electrical and mechanical parts, spare-parts sourcing and contact pages.
