Product Introduction

The design of double row deep groove ball bearings is basically the same as that of single row deep groove ball bearings.

Standard double row deep groove ball bearings are 4200A and 4300A types. A-type bearings do not have a ball gap. Two reinforced nylon cages are inserted from both sides of the bearing. In addition to having a radial load carrying capacity 1.62 times higher than that of single-row deep groove ball bearings, double-row deep groove ball bearings can also bear axial loads.

Three kinds of bearing seals to choice:

(1) OPEN: Maintenance type

Special grease or lubricant for bearing needs to be filled

Applicable to the inside of the machine

(2) ZZ/2Z: Maintenance free

This type of bearing does not require additional maintenance and grease filling

General mechanical, dust-proof

(3) 2RS/DDU:

This type of bearing does not require additional maintenance and grease filling

General Machinery, dust-proof and water-proof

The HAXB bearing catalog lists a large range of designs, variants, and sizes of deep groove ball bearings. Beyond our catalog offering, the HAXB Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.

The following are the different materials of the bearing cages:

Double row deep groove ball bearings are fitted with two glass fiber reinforced nylon 66 cages. SKF suffix is TN9.

Deep groove ball bearings with nylon cages can operate at temperatures up to 120°C.

The characteristics of the cage are not affected by the lubricants used in general rolling bearings, except for some synthetic oils or synthetic oil-based greases and lubricants containing a large number of extreme pressure additives in high-temperature applications.

Double row deep groove ball bearings are suitable for bearing arrangements where the load capacity of a single row deep groove ball bearing is insufficient. For the double row deep groove ball bearing with the same outer diameter and inner diameter as the deep groove ball bearing, its width is larger and the load capacity is also much higher than that of the single row deep groove ball bearing of the 62 and 63 series.

Standard deep groove ball bearings have normal radial internal clearance.

Product Application

(1) Minimum load:

In order to make the bearings run well. Double row deep groove ball bearings, like all ball and roller bearings, must withstand a certain minimum load, especially at high speeds or accelerations, or when the direction of the load changes rapidly. Under these conditions, the inertial forces of the ball and cage and the friction in the lubricant will adversely affect the rolling of the bearing, and a sliding movement between the ball and the raceway that may be detrimental to the bearing may occur.

(2) Precautions for use:

In the case of low-temperature starting or high grease viscosity, a larger minimum load may be required, and the weight of the bearing, plus the external force, usually exceeds the required minimum load. If the minimum load has not been reached, the bearing must be subjected to an additional radial load.

If the double row deep groove ball bearing is to bear pure axial load, it should not exceed 0.5Co under normal circumstances. Excessive axial loads may significantly reduce the bearing service life.
