Parameters
The number of rolling elements is single row, the bearing material is bearing steel, with contact seals on both sides, the radial internal clearance is standard clearance, the cage is made of steel plate, and the net weight of the product is 0.315kg.
Structural features
It consists of an outer ring, an inner ring, a set of steel balls and a set of cages. It has a simple structure, and its manufacturing precision can easily reach a high level. It is convenient for mass production and has a low cost.
There are two types: open type and sealed type. The sealing type is further divided into dustproof seal and oilproof seal. For example, 62305-2RS indicates a deep groove ball bearing with nitrile rubber seals on both sides, which can effectively prevent dust and impurities from entering and grease from spilling out.
Performance characteristics
Mainly bear radial load, and can also bear certain axial load at the same time. When the radial clearance of the bearing is increased, it has certain angular contact ball bearing performance and can bear greater axial load.
The friction coefficient is small, which can reduce energy loss, improve mechanical efficiency, reduce heat and wear, and is suitable for occasions with low friction requirements.
The limit speed is high, suitable for high-speed rotating parts, and can maintain stable operating performance at high speed.
It has certain self-aligning ability. When it is tilted 2′-10′ relative to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing.

Deep Groove Ball Bearings Introduction:
Deep groove ball bearings mainly take radial load as well as take moderate axial load. With less coefficient of friction, high limiting speed, large size range and colorful combination of structure; they are suitable for tractor, motors, automobiles, motorcycles, and other common machinery, as a widely used type of bearings in machinery industry.
Deep groove ball bearings are suitable for high-speed or even extremely high-speed operation, and are very durable without frequent maintenance. This type of bearing has a small friction coefficient, high limit speed, and various size ranges and forms. It is used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used type of bearing in the machinery industry. Mainly bear radial load, but also can bear a certain amount of axial load.

Frequently Asked Questions (FAQ)
The 62305 deep groove ball bearing features boundary dimensions of 25mm bore diameter, 62mm outer diameter, and 17mm width (24mm for specific variations), with a net weight of approximately 0.315 kg.
The 62305 bearing provides a basic dynamic load rating (C) of 22.5kN and a basic static load rating (C0) of 11.6kN. It primarily carries radial loads but can also accommodate bidirectional axial loads.
Sealing options include Open, ZZ (metal shields), and 2RS (contact nitrile rubber seals on both sides) for superior protection against dust, contaminants, and grease leakage.
The 62305 bearing has a limiting speed of 7500 r/min, making it ideal for high-speed operation in electric motors, gearboxes, and precision instruments.
Yes. Standard models use Chrome Steel GCr15 with pressed steel cages, but custom brass, steel, or nylon cages, varied clearance/precision grades (P0-P4), and OEM branded packaging services are available.
For order quantities between 1 and 300 pieces, the estimated lead time is approximately 2 days. For orders exceeding 300 pieces, delivery times can be negotiated.
