Construction and bearing components

Deep groove ball bearings

ZGSLThe basic structure consists of two bearing rings, rolling elements and for holding the rolling elements equidistant rolling cage. Seals and dust cover is used to prevent dust or foreign matter intrusion of oil. The main purpose is to reduce the use of lubricant friction and wear of the rolling element.

Cage

Holder in operation be subject to mechanical friction effect, the inertia force and tension, while also subjected to the chemical action of certain lubricants, additives, solvent, or cooling agent. Therefore cage design and material bearing on its performance and reliability has a crucial role.

ZGSL deep groove ball bearing retainer is divided into the following categories:

Rivet type cage

Curved jaw holder

Synthetic resin material holder

By the precision with bold metal

forming.Becomes spherical pocket

holder, andIt will be fixed with

rivets. Usually usedZGSL sized

deep grooveball bearings.

By the precision strip stamped and formed into a spherical pocket holder and is curved claws. Two teams from the cage caulking. Typically used for HCH miniature deep groove ball bearings.

Synthetic resin cage had a

lot of material Mix from the

system, suchas with a glass

fiberNylon PA66, having

lubricatingPerforma-nce

and low noise. Usually used

ZGSL base noise bearings.

Inner structure

ZGSL bearing inner ring structure has the following three：

V-groove structure	L-shaped groove structure	Flat structure

Dust and seals

Sealing performance of the lubricant cleanliness and bearing life plays an important role in the internal seal bearing structure must be designed to prevent the invasion of foreign bodies and lubricant leakage. In the case outside of the bearing can not be sealed, usually with a seal bearing structure.

Different inner structure corresponding to form a seal：

V-groove Series

Steel dust cover （ZZ） Steel dust cover for outside Better Ministry of environment of the occasion;The use of high-speed operation of occasions;	Non-contac trubber seals（2RZ） Sealing performance in general, the use of the external environment is relatively high occasions. Starting torque of the occasion;	Rubber seal lips touching （2RS） Good sealing performance, the use of the external environment is harsher occasions;Jiaotong starting torque, speed is generally used for the occasion.	Rubber seal, single lip touch （2RW） Optimum sealing perform ance, can be used in sealingthe new requirements of the occasion; starting torque small, for use in high speed situations;
L-slot series

Note: 1, the above seal structure for reference only, to prevail in kind.
2, seals and dust cover material can be changed according to customer requirements.
3, ZGSL main forms listed above seals, special-purpose special structural design. Please contact ZGSL technical department when needed.
