Oil-impregnated polyacetal multi-layer bearings with back metals .Free I Test data Journal rotation test Feature • Serviceable without the need for lubrication and demonstrates low coefficient of friction and superior load performance. • Demonstrates superior wear resistance in applications where oil film is seldom produced such as reciprocating motions, oscillation, frequent starts and stops, etc. • Thin bearing allows compact design. • Superior dimensional stability, mechanical strength, and thermal conductivity. • The standard products and plate material of various sizes are available. 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]). ^The values shown above are typical values, not the standard values. ^The values shown above are values of back metal. Lathe turning carbide tool (JIS) Attention should be paid to dimensional variances due to thermal expansion, chucking, and bend of the material. 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. <Testing conditions> Mating material : S45C (surface roughness Rz0.6jum) Lubrication : grease is applied at assembley Journal oscillation test_ <Testing conditions> Bearing dimension : 04OX044X R 30(Oiles Drymet ST) 04OX05OX R 30(Oil impregnated sintered bronze bearing) Mating material : S45C (surface roughness Rz1.5jum) Pressure : 19.6N/mm2|200.0kgf/cm2| Oscillating cycle : 100cpm Oscillating angle : 20° Oscillating frequency : 300,000cycle Lubrication : grease is applied at assembly Test time[hrs.)

Press-fitting with guide ring Inner diameter of the guide ring should be the size so that the bushing can be inserted by hands. Length of the guide ring should be more than one-third of the bushing, or if possible, it should be the same length as the bushing. Figure 1 The dimension of guide ring should be calculated from table below. Dimension of bushing Guide ring I.D. 3. The "GO" ring gauge stands for the upper limit and the "NO GO" ring gauge the lower limit of the O.D. tolerance. 4. Chamfering: Both ends of the I.D. and O.D. are chamfered as shown in the right diagram except those with the...
