BL310 NR Single Row Deep Groove Ball Bearing BL310NR Size 50x110 X 27 Mm
Deep groove ball bearing introduction:
Deep groove ball bearings mainly bear radial loads and also bear moderate axial loads. Small friction coefficient, high limit speed, large size range, large structure change, suitable for common machinery such as precision instruments, low-noise motors, automobiles, motorcycles, etc., as a widely used bearing type in the machinery industry.
Sealed deep groove ball bearings Deep groove ball bearings
with sealed discs (contact washer) or covered discs (non-contact washer) allow a simple design. Bearings are supplied with one and two sealed or covered discs. Bearings with washers on both sides are filled with high-quality grease. Sealed bearings can be used from -30 °C to the maximum temperature range. 110 °C (short term) for contact, and up to max. 120 °C for non-contact gaskets. It should be noted here that at permanent temperatures > 70 °C the service life of the grease will be reduced. A special grease is provided for this case.
Deep groove ball bearings
with annular grooves in the outer ring Deep groove ball bearings with annular grooves in the outer ring simplify the design in many cases, since they can be simply fixed and axially fixed in the housing by snap rings to save space. These bearings are available with or without snap rings only on request.
Deep groove ball bearing noise testing
As standard, deep groove ball bearings are subjected to noise testing up to drilling parameter 12. In addition, a 100% rolling test is performed. These bearings can also be noise tested if requested by the customer (on request only).
Deep groove ball bearings without a cage
suffix have a steel plate cage. Different cage designs are indiexcavatored on the bearing type as the bearing symbol (suffix). Deep groove ball bearings with glass-fiber-reinforced polyamide 66 cages are suitable for extended periods at temperatures up to 120 °C. When using oil lubriexcavatorion (for unsealed bearings), if the temperature exceeds 100 °C for a long time, the additives contained in the oil may affect the service life of the cage. Furthermore, deep groove ball bearings with brass cages and galvanically insulated designs are available on request.
Single row deep groove ball bearings accept radial and axial forces, so they can be used in a wide range of appliexcavatorions. They have a simple design, are self-retaining, suitable for high to very high speeds and resistance during operation and maintenance, and they are available at very favorable prices. Due to these characteristics, self-aligning deep groove ball bearings are the most used antifriction bearings. The standard version of SLF deep groove ball bearings has grooves for inserting sealing and/or covering discs. The only exception is the series 160.... Here, only versions without sealing and/or overlay disks are available. (exception 16006.2ZR)
