Is MR.149 interchangeable with MR.148G2?

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 MR.149 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.
