INA NA4902-XL 滾針軸承

Overview

INA NA4902-XL Needle Roller Bearing is a compact bearing designed to carry high radial load within a small cross-section. It is suitable for gearboxes, automotive transmissions, industrial links, and pivot positions where space saving and load capacity are both required.

Long, small-diameter rollers are arranged in a cage or full-complement design. Versions with or without inner rings are available, and shaft hardness and surface finish are critical when the shaft is used as the raceway.

Selection guidance

Check mounting envelope, inner ring requirement, shaft surface hardness, lubrication, load, and speed range.
