The 4.056+AP2-Q is a standard axially fixed composite roller bearing equipped with a black square mounting plate. Its standard outer diameter is 77.7mm, and customized larger sizes including 78.1mm and 81.8mm are also in stock.
This bearing series is extensively applied in heavy-duty linear guide systems, covering forklift masts, stacker cranes, intelligent automated production lines and other mechanical transmission equipment.
Adopting a standard square mounting plate, the AP2-Q can be directly installed on equipment frames. Precisely processed threaded holes on the plate enable direct bolt fastening, eliminating extra complicated machining procedures. Besides, rectangular mounting plate version is optional.
Its integrated composite roller structure is capable of bearing combined radial and axial loads at the same time. The bearing is axially positioned and matched with 2Nbv series guide rails made of 20MnV steel material to maintain stable and smooth sliding operation.
Standard ring seal configuration is adopted for internal protection. Meanwhile, customized sealing solutions can be provided according to clients’ special working environments.
The steel mounting plate undergoes blackening surface treatment to achieve excellent rust prevention and corrosion resistance. In addition, galvanized and chrome-plated plate alternatives are available upon request.
