Machinery transmission link joint bearings supporting M12 * 1.75 by self-lubricating bearing (inner sphere chrome) Spherical plain copper ring gasket extending threaded rod (zinc coated) components. Divided by lubrication self-lubricating joints and parquet fisheye pad (without nipples) (with nipple); according to thread into the right-handed and left-handed direction (L plus "L" mark); pressing screwed into the internal thread and location external threads. Machinery transmission link joint bearings supporting M12 * 1.75 widespread use of facilities in various engineering machinery, hydraulic steering with power and other institutions. Can withstand greater load bearing a connection control, you can rotate the swing, easy for a variety of rod movement. According to their different types and structures to withstand radial load, axial load or radial, axial joint load simultaneously, there is a greater load capacity and impact resistance, impact resistance, corrosion resistance, wear self-aligning, lubrication is good.
