Skf M/5903655 Ball Transfer Unit 25mm Stainless Steel

Product Description

The SKF M/5903655 is a stainless steel ball transfer unit designed for conveyor, material handling, and industrial positioning applications. It features a 25 mm stainless steel ball housed in a stainless steel round base with a bolt-on mount configuration. The unit measures 39.70 mm in overall housing diameter and delivers a mount height of 32.50 mm, keeping the transfer ball in a fixed upward-facing working orientation. The M8 threaded bolt-on mount with a 25 mm thread length allows for secure single-hole fastening to conveyor frames, work tables, or custom fixtures. This unit is installed by millwrights, maintenance technicians, and industrial assembly professionals.

The M/5903655 is suited for light-to-medium duty material handling systems where smooth omnidirectional movement of parts, panels, or packages is required. Its all-stainless construction makes it appropriate for food processing, wet environments, cleanroom conveyor lines, and other corrosion-sensitive installations. The ball-up working orientation is the standard configuration for flat conveyor bed and table-top integration, allowing product to glide across the transfer surface with minimal friction and precise directional control.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation ball transfer unit for industrial conveyor tables, assembly fixtures, and material handling systems requiring a 39.70 mm round-base bolt-on unit with an M8 mounting thread.

Installation Notes

Installation is performed by millwrights or maintenance technicians familiar with conveyor and material handling equipment. Ensure the mounting surface is clean and flat before securing the unit with an M8 fastener through the single mounting hole. Confirm the transfer ball spins freely after torquing the mount to avoid bearing preload that restricts movement. Disconnect or lock out all conveyor drive systems before installing or replacing ball transfer units on live lines.
