Overview: This document provides technical specifications for Minebea's self-lubricating sleeve bearings, specifically the MJF-A and MJF-C models. These bearings are designed with a flanged sleeve and are available in two material options: anodised or alodined aluminium alloy and 410 stainless steel, both featuring a Teflon (TFE) liner.

Materials: The sleeve is made from either aluminium alloy or 410 stainless steel, with a Teflon liner permanently bonded to the sleeve's interior diameter (I.D.).

Specifications: The document lists detailed dimensions for various part numbers (MJF06 to MJF50), including diameter tolerances and weight calculations based on length (L). The aluminium sleeves have a tolerance of ±0.013 mm, while stainless steel sleeves have a tolerance of 0 to -0.013 mm.

Dimensions: The dimensions are provided in millimeters, with specific measurements for outer diameter (φB), flange diameter (φD), flange thickness (F), and other critical dimensions (φH, φE). The weights are calculated using formulas that incorporate the length of the sleeve.

Notes: The document specifies that these bearings are made to order and advises consulting Minebea for availability. It also mentions that the I.D. size should be inspected using a plug gauge.

Length Options: The document provides a comprehensive list of available lengths for each part number, with tolerances specified as ±0.2, ±0.3, or ±0.5 mm depending on the length.
