This type is the most common roller bearing a kind of open bearings, also known as flat bearings, bearing both itself without seals, idlers already has several layers of protection nylon rollers, bearing seals sealing performance has been very good, bearing coupled with superfluous seal, open roller bearing easy to install their own before the actual situation grasp roller bearing grease filling quantity lubricating oil. Open roller bearing roller bearing costs than with seals also have a certain price advantage. Easy to improve market competitiveness and even roller conveyor
2. Host Requirements related parts
Roller bearings where the rotary bearing system requirements through precise balancing, shaft and bearing housing bore installation site should have a higher than normal requirements for dimensional accuracy and geometric accuracy, concentricity and in particular to stop the shoulder seat hole or journal verticality, and in considering these questions, the same factors must be noted that high-speed and high temperature operation is bearing factor.
Shaft support systems require both high rigidity and quality requirements as light as possible, in order to overcome this contradiction can be taken to improve the surface roughness and surface hardening and other measures such as reducing the stiffness of the support in order to improve the use of hollow shaft to reduce system quality |
