Rolling bearings tolerances on main dimensions, tolerances and rotation precision, in the GB and ISO standards are required. Bearing precision grade in addition to the general accuracy level PO, P6, P5, P4, in turn improve precision grade. These precision according to ISO specification. Table 1,2 column I produced PO stainless steel bearings (not including plastic bearings) corresponding tolerances and value, the P6, P5. P4 tolerances please contact with the company.
Plastic bearing due to machining precision and dimensional stability limit itself ( coefficient of thermal expansion than ceramic and metal material ) according to below the PO level tolerance production. Table 3 lists the company production of plastic bearing the corresponding tolerance value.
