What thin section bearing lubrication is intended to join

thin section bearing is a rolling bearing, use the time to reduce internal friction and wear of the bearing to prevent burning stick, you need to add the lubricating effect, adding the purpose of lubrication to ①reduce friction and wear ② in the ring, and the rolling elements constituting the bearing retainer mutual contact portions to prevent the metal contact, reducing friction, wear ③ fatigue life of rolling fatigue life, in rotation, the rolling contact surfaces oiled, will be extended. Conversely, low oil viscosity, poor lubricating film
thickness is shortened discharge of frictional heat, cooling ④ circulating oiling method, etc. can be discharged oil heat generated by friction or heat coming from the external cooling. Prevent bearing overheating and prevent oil itself aging ⑤ to prevent dust and debris inside the bearing, or prevent rust, corrosion effect.

slewing ring bearings are nearly four decades the gradual rise

slewing ring bearings are nearly four decades the gradual rise in the world of new mechanical parts, which have inner and outer rings, rolling, etc., is a comprehensive large bearings to withstand load, can withstand large axial, radial load and tilting moment. Slewing ring in reality very broad industrial applications, known as: "the machine joint" is subject to the relative rotational movement between the two objects, and the need for simultaneous axial and radial forces, tilting moment by machinery required important transmission components. With the rapid development of the machinery industry, the slewing ring in marine equipment, engineering machinery, light machinery, metallurgical machinery (metallurgical bearing), medical equipment, industrial machinery and other industries has been widely used.

Thin slim ball bearing characteristics

slim ball bearing to achieve a very thin section bearing, but also to achieve a product miniaturization and lightweight. Diversity of products has expanded its range of purposes. In order to obtain a low friction bearing torque, high rigidity, good rotary precision, small diameter steel balls. Using a hollow shaft, ensuring lightweight space and wiring. Thin wall bearing rings were deep groove ball bearings, four point contact bearings, angular contact ball bearings. In different series are available in a variety of dollars more. Series depends on the cross-sectional size. Match ball and series. Deep groove ball bearings can support bi-directional axial load and radial load.

How to store the correct slewing ring bearings

slewing ring bearings, it can withstand a large axial load, radial load and overturning moment large bearings. Generally with mounting holes, internal gears or external gears, lubricants holes and sealing devices, which enable the host compact design, guide reliable, and easy to maintain. However, because the user does not pay attention slewing transportation, and other storage, installation and maintenance details, resulting in performance degradation host phenomenon can not be ignored. Slewing rings coated with anti-rust oil at the factory, and with the film wrapped, the packaging rust usually valid for 3-6 months, it should be raised year after inventory grease and check rotation flexibility, not collision and squeeze, not rain, storage should be smooth. It should be stacked flat isolation between slewing ring. Slewing ring generally have lifting holes, you can secure the lifting eyebolts screwed.

Characteristics and principles of presentation slewing bearing

Slewing ring turntable bearings, also known, is a comprehensive large bearings to withstand load, can withstand large axial, radial load and overturning moment. Wheel bearings in general with mounting holes, internal gears or external gears, lubricants holes and sealing devices, which enable the host compact design, the guide is simple, easy to maintain. Have toothed wheel bearing, external tooth and internal tooth four-point contact ball bearings, double row angular contact ball bearings Crossed cylindrical roller bearings, tapered roller bearings and cross three-row cylindrical roller bearings four series compound , the wheel bearings large rotary devices are widely used in lifting machinery, mining machinery, construction machinery, port machinery, ship equipment and high-precision radar and missile launchers and other mechanical equipment. But also according to the user's specific requirements and design, development and production of special structures wheel bearings.

Spherical roller bearings and tapered roller bearings are characterized by role

Spherical roller bearings with two rollers, the main receiving radial loads, but also can accept either direction axial load. A high radial load capacity, especially suitable for heavy loads or vibration, but can not accept the pure axial load. This kind of bearing outer ring raceway is spherical shape, so the good performance of its self-aligning, can compensate concentricity error. Tapered roller bearings are mainly used to accept radial load mainly radial and axial load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can accept axial loads in one direction, a direction to limit the axial displacement of shaft or housing.

Commonly used thin-walled rings bearing

Thin wall bearing rings can be deep groove ball bearings, four point contact bearings, Angular contact ball bearings. In different series are available in various designs over. Series depends on the cross-sectional size. Match ball and series. Deep groove ball bearings can support bi-directional axial load and radial load. four point contact ball slewing bearing can support bi-directional axial load and radial load; therefore they are in contact with the same operating mode double row angular ball bearing. Angular contact ball bearings can match the optimal number of balls and the contact angle of 30 °. They support radial loads than deep groove ball bearings or four point contact bearings higher, and can support axial loads from the same direction. For special needs, angular contact ball bearings are also available as matched bearings provide. Therefore, rigidity and load carrying capacity of these combinations than single bearing products to be much higher.
