Technical Product Corporate Profile Information Slide Shifter Air Bearings Metallic Bearing BMBEBBBBBaBalBM Plastic Bearing Information Selection Guide Oiles Techmet B Polytetrafluoroethylene plastic multi-layer bearings with back metals -Sliding surface ^Unusable under the condition of water, splashing water and high humidity. Feature • Serviceable without the need for lubrication. Features superior dimensional stability, mechanical strength, and thermal conductivity with a thin, lightweight, and compact design. • Demonstrates stable low coefficient of friction and superior wear resistance under high-speed conditions. • The plastic layers have machining allowance, allowing high dimensional accuracy when the inner diameter is machined. • The standard products in various sizes are available on order. Polytetrafluoroethylene plastic layers with filler Sintered bronze layer Back metal Service range The values in parentheses are static bearing pressures, which are the bearing pressures in applications with no motion or very small motion (^0.0017m/s [0.1m/min]). Mechanical properties ^The values shown above are typical values, not the standard values. >SThe values shown above are values of back metal. ®Please refer to the fitting method of Drymet LF. (P.153, 154) Lathe turning carbide tool (JIS) Attention should be paid to dimensional variances due to thermal expansion, chucking, and bend of the material. The Oiles Techmet should be ground. If it is reamed, it is difficult to maintain the dimension in mass production. The I.D. machining allowance is 0.2 mm for the diameter. Machining accuracy (bushing) (Note) Accuracy after press fitting. Classes here are in JIS standard. This product demonstrates satisfactory performance at the slide surface roughness of Rz6.3 to 12.5jum. Dimensions may change due to thermal expansion, chucking pressure, moisture absorption deformation, etc. High accuracy is ensured if the product is installed on the housing and then ground.
