Product Description

Product Overview

MISUMI economy free rollers do not have their own power source and mainly rely on conveyor belts or chains to rotate, serving to support the conveyor belt and guide product transport. They are an indispensable component of conveyor and drive systems.

Feature 1: Flexible installation, compact and lightweight; suitable for both frames and conveyor lines. Small size, light weight, and low installation space requirements.
Feature 2: Various materials for a wide range of applications; available with carbon steel or stainless steel rollers, and can be coated with PU or PVC on the surface. You can choose different combinations based on the characteristics of the usage environment.
Feature 3: Simple structure and easy maintenance; mainly composed of the drum body, bearing housing, bearings, and main shaft, resulting in an extremely low failure rate and very convenient daily maintenance and replacement.

Alterations

Alterations	Motorized Roller Accessory Shoulder Sleeve
Code	SS	Depending on the roller surface length, 1 to 5 additional shoulder sleeves can be added. Specification method (example): SS3-A100-B300-C500 The dimensions A, B, C, D, and E in the left diagram represent the distance from each collar to the drive end reference point, specified in units of 1 mm. If there are 2 collars: only define A and B If there are 3 collars: only define A, B, and C If there are 4 shoulder sleeves: only define A, B, C, and D. If there are 5 shoulder sleeves: define A, B, C, D, and E.
Spec.	POK (Black polyoxymethylene)
	D80*W100


	A number after the code indicates the quantity of shoulder sleeves.

Installation Instructions

Internal thread:
1. This is the most commonly used installation method for powered conveyors such as sprocket rollers,
The roller and the frame are connected into a single unit by bolts at both ends.
2. Installing and removing the roller takes relatively more time.
3. The mounting holes on the frame should not be too large to minimize the height difference of the roller after installation (the gap is generally set to 0.5 mm,
For example, for M10, it is recommended that the frame hole diameter be ⌀10.5 mm);

Example of Use

Application Areas
Free rollers are widely used in fields such as warehousing and distribution, food packaging, automotive parts manufacturing, airport equipment, logistics sorting, and new energy. When paired with motorized rollers or belt conveyors, they provide material support and ensure smooth conveying operations.
