Nadella GCL62 滚轮 24 × 62 × 30.6 mm

Overview

NADELLA GCL62 Track Roller is a rolling bearing whose thick outer ring rolls directly on a cam track, guide rail, or rocker arm contact surface. The needle- or cylindrical-roller assembly inside the heavy outer ring tolerates shock load and vibration, with yoke-type (bore + external pin) and stud-type (integral threaded shaft) variants covering most mounting configurations.

The outer ring is intentionally heavy so it can run directly against a track surface, with a cage of needles or cylindrical rollers inside. Yoke-type rollers mount on a separate pin or bolt-shaft; stud-type rollers carry an integral threaded stud and install as a single part.

Selection guidance

Consider mounting style (yoke vs stud), outer-ring profile (cylindrical or crowned), track surface hardness, load direction and speed, and lubrication / sealing requirements.
