Product Overview
This stainless steel U-groove bearing roller combines an SS420 or 440C stainless steel inner bearing with a machined stainless steel outer ring. The outer ring can be produced from SS420, SS304 or another approved material according to the required contact, wear and corrosion conditions.
The internal ball bearing supports rotation while the concave running surface follows a compatible round rail, belt, cable, tube or shaped guide. Matching the groove to the contacted component helps keep it positioned within the intended running path.
This product is suitable for automation equipment manufacturers, guide-system suppliers, material-handling equipment companies and OEM customers requiring a compact bearing-integrated stainless steel guide roller.
Selection should be based on the bearing bore, roller outer diameter, overall width, groove radius, mating-surface diameter, load direction, operating speed and working environment. The final specification should be checked against a drawing, sample or actual installation position.
Applications
Round Rail and Guide Track Systems
The U-groove roller can follow a compatible round rail or shaped track in compact guiding and positioning assemblies.
Round Belt, Cable and Tube Guidance
The curved groove can guide a matching round belt, cable or tube when the groove radius, contact conditions and installation arrangement have been confirmed.
Automation and Material-Handling Equipment
The roller can perform guiding or positioning functions in production machinery, transfer mechanisms and compact material-handling assemblies.

Advantage
U-Groove Running Profile
The concave running surface is designed to match a compatible round rail, belt, cable or tubular guide. The groove radius, depth and opening width can be adjusted according to the mating geometry.
Selectable Stainless Steel Materials
The inner bearing can be specified in SS420 or 440C stainless steel, while the grooved outer ring can be produced from SS420 or SS304. 440C can be considered where higher hardness and wear resistance are required after appropriate heat treatment, while SS304 can be evaluated where corrosion resistance is the main priority.
Bearing-Integrated Rotation
The internal ball bearing allows the grooved outer ring to rotate around the mounting bore. The bearing specification, wheel dimensions and mounting arrangement can be developed together for the customer’s assembly.

How to Choose
-
1
Confirm the Mating Surface
Identify whether the roller will contact a round rail, belt, cable, tube or another shaped guide. Different contact surfaces require different groove geometry.
-
2
Match the Groove Geometry
Confirm the groove radius, depth and opening width. An incorrectly matched groove may produce unstable guidance or concentrated contact.
-
3
Confirm the Roller Dimensions
Provide the bearing bore, roller outer diameter and overall width according to the available installation space and mounting arrangement.
-
4
Select the Stainless Steel Combination
Choose SS420 or 440C for the inner bearing and SS420, SS304 or another approved grade for the outer ring according to the required hardness, wear and corrosion conditions.
-
5
Confirm the Mounting Method
Specify the axle or bolt diameter, installation clearance, retention method and any surrounding bracket or housing dimensions.
-
6
Validate a Sample
Test the roller with the actual rail, belt, cable or guided component before approving bulk production.
