Bearing Is An Important Part Of Mechanical Equipment. Its Main Function Is To Support The Mechanical Rotating Body To Reduce The Mechanical Load Friction Coefficient Of The Equipment In The Transmission Process.
The Difference Between Deep Groove Ball Bearings And Tapered Roller Bearings |
Deep groove ball bearing formerly known as single-row radial ball bearing, is the most widely used rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial simultaneous action of the combined load on the machine parts, can also be used to bear axial load on the machine parts, such as small power motor, automobile and tractor transmission, machine tool gearbox, general machines, tools, etc | |
Tapered Roller Bearing: Low Limit Speed, Used In Automobile, Rolling Mill, Mining, Metallurgy, Plastic Machinery And Other Industries |


Deep Groove Ball Bearing is One of the Most Widely Used Rolling Bearings
Deep groove ball bearings are the most common type of rolling bearings .The basic type of 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 bearing, single row and double row, deep groove ball structure is also divided into sealed and open two structures, open refers to the bearing does not have a sealed structure, sealed deep groove ball is divided into dust seal and oil seal. The dust seal cover material is steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the leakage of grease in the bearing.Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.

It can prevent the intrusion of any foreign matter and has a strong dust-proof effect. It is recommended for use in harsh environments.

Compared with rubber seals, the speed is higher and the dust-proof effect is good. It is recommended when there is dust and no liquid impurities.

Q4: How to customize bearing(non-standard) from your company?
A: We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.
Q5: What should I care before installation?
A: Normally, the preservative with which new bearings are coated before leaving the factory does not need to be removed; it is only necessary to wipe off the outside cylindrical surface and bore, if the grease is not compatible with the preservative, it is necessary to wash and carefully dry the bearing.Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.
Q6: How to stock and maintenance my bearings right?
A: Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity or sudden and severe temperature changes that may result in condensation forming;Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
