YDTech® rollers for fuel pump, diesel oil pump,gasoline pump, motor driven pump! cylindrical rollers for water pump, lubricating pump,power steering pump, brake pump!
rollers for fuel pump application:fuel pump, diesel oil pump, gasoline pump, motor driven pump, water pump, lubricating pump, power steering pump, brake pump, automobile turning power pump, ethanol fuel pump for automobile, self priming oil pump.
cylindrical rollers in air or hydraulic cylinders is typically limited to a supporting role, rather than a primary sealing element. Their use can help improve the performance and longevity of the primary sealing element, but they should not be relied upon as the sole sealing element in these applications.
cylindrical rollers are typically not used as the primary sealing element in air or hydraulic cylinders, as they are not designed to withstand the pressures and forces involved in these applications. Instead, cylindrical rollers are often used as a supporting element in conjunction with other sealing elements.
application: precision rail type cylinders, precision rail type cylinders, roller type relay, lift valve groups, mechanical flow valve, pneumatic finger, gripper cylinders, electromagnetic flow valves, precision measuring platform, optical measuring instrument guide, manual displacement platform, electric displacement platform, cross rail table, precision cylinder cylinder, linear bearing rail, slide cylinder, rodless cylinder,
we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.
