Product Description

Deep Groove ball bearing

Deep Groove Ball Bearing china supplier ORIGINAL KOYO Bearing Bl307 Bl307nr Bl307znr Bl307zz 

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of cages. There are two types of deep groove ball bearings: single-row and double-row. The deep groove ball structure is also divided into two types: sealed and open. The open type means that the bearing does not have a sealed structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof. seal. The material of the dust-proof sealing cover is stamped steel plate, which only serves to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

Single row deep groove ball bearing type code is 6, double-row deep groove ball bearing code is 4. It has a simple structure and is easy to use, and is the most commonly produced and widely used type of bearing.

Applications	Cars, trucks, and trailer bearings are widely used in cars, trucks, and trailers of various transmission / rotating members.
Special Properties	1. High precision
	2. Low noise
	3. long life
	4. Can be customized according to your needs
	5. Can provide small & miniature standard and non-standard bearings.

Linear bearings, manufactured at low cost, are used in limitless journeys or used to work in columns. As the loading ball contacts the shaft at a certain point, the bearing application loading capacity is quite small. With balls rotating with quite small friction resistance, high-precise level movement can be obtained. Linear bearings are widely used in precise equipment such as electronic equipment, pull measuring machines, materialization 3-D measuring equipment, etc; and slip parts of industrial machines such as multi-shaft machines, punching machines, tool grinders, auto steam cutting machines, printers, card selection machine, food packing machine and so on.
