Deskripsi produk

stainless steel NA4903 sealed needle roller bearings 17*30*13mm for Machinery Construction Farm Industries 

NA4903 is a needle roller bearing with a separable design (the inner ring and needle roller assembly can be removed from the outer ring), featuring standard internal clearance, and is typically supplied unlubricated. Its core design relies on needle rollers—small-diameter, high-length rollers that enable it to withstand heavy radial loads while occupying a compact radial space. The separable structure facilitates easy installation, maintenance, and replacement, as the inner components can be handled independently from the outer ring.
The needle rollers are manufactured with high surface finish and dimensional accuracy, ensuring uniform load distribution across their contact areas with the inner and outer rings. This design not only maximizes load-carrying capacity but also minimizes friction operation even under high-speed or intermittent load conditions. The standard internal clearance balances rotational flexibility and load stability, while the unlubricated supply format allows users to select optimal lubrication based on operating temperatures, speeds, and environmental demands.

Sizes:

17mm ID × 30mm OD × 13mm Width

Interchange:

NA4903 (cross-brand equivalents such as SKF NA4903, NSK NA4903, Timken NA4903), and needle roller bearings with identical "17mm ID + 30mm OD + 13mm width" specifications

Applications:

Machinery, Construction, Farm Industries, as well as Automotive Components, Small-Scale Engineering Machinery, and other scenarios where high radial load capacity and compact installation space are critical.
