Flat end needle rollers feature planar end faces with profiled or slightly chamfered edges to minimize edge stress during operation. They are the most widely used end configuration in general-purpose bearing applications, offering excellent load distribution and ease of installation.
We are a specialized manufacturer of loose needle rollers with flat ends – commonly designated as NRB type in the industry. Unlike traders or distributors, we control the entire production process in-house, from raw material selection to final inspection. This allows us to deliver consistent quality, competitive pricing, and flexible lead times for both standard and custom orders.
Our flat end needle rollers are precision-engineered components used as rolling elements in bearings, as well as standalone mechanical parts such as pivot pins, locating dowels, and shafts in compact assemblies. We supply to customers across the automotive, industrial gearbox, hydraulic pump, agricultural machinery, and aerospace sectors.

All our flat end needle rollers are made from high-grade bearing steel, primarily 100Cr6 (AISI 52100), hardened to 60–66 HRC with a uniform case depth. We also offer stainless steel (AISI 440C) and ceramic materials for corrosion-resistant or high-temperature applications upon request.
Our quality assurance system is certified to IATF 16949 and ISO 9001, with 100% dimensional inspection performed using automated optical sorting machines and precision micrometers. Every batch is tested for hardness, surface roughness, and geometric tolerances (roundness, cylindricity, and end-squareness) to ensure full traceability and compliance with your specifications.
