Execution guidance

Standard design and inspection

Design function

A fixed axial roller supports combined radial and side load in a compact mast-guide envelope.

Installation and adjustment

Set running clearance through the mating profile and mounting position; the axial roller itself is not eccentric-adjustable.

Inspection focus

Verify radial OD, overall height, axial-roller position, stud geometry and smooth rotation.

Application

Application and RFQ checklist

Material-handling masts, lifting columns, AS/RS systems and steel guide profiles.

4.056 combined bearing FAQ

Model Questions

Is 4.056 interchangeable with MR0023?

The references are commonly associated with the same product family, but interchangeability must be confirmed from d, D, H, mounting details, axial-roller execution, load and operating conditions before ordering.

What information is required to quote a 4.056 combined bearing?

Send the full marking, quantity, delivery country and, where possible, a bearing photo or drawing. We verify the dimensional envelope and fixed, precision or adjustable execution before quotation.

Is this an official WINKEL product?

Combined Bearing Source manufactures factory-compatible replacements. WINKEL and other brand references are used only to identify the requested model. The supplied product is a factory-produced compatible bearing unless an original branded product is expressly quoted.
