3007 B 2RS ZEN 35x62x20 Double Row Angular Contact Ball Bearing

What Is the 3007 B 2RS ZEN Bearing?

The 3007 B 2RS ZEN is a double row angular contact ball bearing with dimensions 35x62x20 mm, designed to accommodate combined radial and axial loads. Its double row construction allows axial loads to be supported in both directions while providing stable shaft guidance. The 2RS design features seals on both sides of the bearing, helping retain lubricant and protect the rolling elements against dust and contamination.

What Does 3007 B 2RS Mean?

The bearing designation provides important information about its construction:

• 3007 - double row angular contact ball bearing series
• B - 25° contact angle for this ZEN version
• 2RS - seals on both sides
• ZEN - bearing manufacturer

The double row arrangement allows the bearing to support axial forces acting in both directions in addition to radial loads.

Why Use a Double Row Angular Contact Ball Bearing?

A double row angular contact ball bearing is particularly useful in applications where radial and axial forces occur simultaneously.

Its construction provides:

• Radial load carrying capability
• Axial load carrying capability in both directions
• Stable shaft guidance
• Good rigidity
• Compact bearing arrangement
• Combined load capability

In suitable applications, a double row bearing can provide a compact alternative to an arrangement using two separate single row angular contact bearings.

Typical Applications

The 3007 B 2RS ZEN can be used in:

• Industrial gearboxes
• Pumps
• Industrial machinery
• Production equipment
• Agricultural machinery
• Conveyor systems
• Drive systems
• Industrial automation
• Machine tools
• Mechanical equipment

It is particularly useful where a rotating shaft is subjected to combined radial and axial forces.

2RS Sealing

The 2RS suffix indicates seals on both sides of the bearing.

The seals help to:

• Protect rolling elements against contamination
• Reduce the ingress of dust and dirt
• Retain lubricant inside the bearing
• Reduce maintenance requirements
• Support reliable operation in industrial environments

This design is useful in applications where an open bearing would be more exposed to external contamination.

Radial and Axial Load Capacity

Unlike a conventional deep groove ball bearing, an angular contact bearing has specially designed raceways that allow forces to be transmitted at an angle relative to the radial plane.

The 3007 B 2RS ZEN has a 25° contact angle. This geometry enables the bearing to accommodate combined loads.

Because it has two rows of balls, axial loads can be supported in both directions while radial loads are carried simultaneously.

Installation Recommendations

Before installation, verify:

• Shaft diameter of 35 mm
• Housing bore of 62 mm
• Required shaft and housing fits
• Alignment of the shaft and housing
• Condition of mounting surfaces
• Expected radial and axial loads
• Operating speed and temperature

During press fitting, installation force should always be applied to the bearing ring with the interference fit. Mounting forces should never be transmitted through the balls and raceways.

Frequently Asked Questions (FAQ)

What are the dimensions of the 3007 B 2RS ZEN?
The bearing has a 35 mm inside diameter, 62 mm outside diameter and 20 mm width.

Is the 3007 B 2RS a double row bearing?
Yes. It is a double row angular contact ball bearing.

What does 2RS mean?
2RS indicates that the bearing is equipped with seals on both sides to help retain lubricant and protect the internal components against contamination.

What does B mean in 3007 B 2RS ZEN?
For this ZEN version, the B designation indicates a 25° contact angle.

Can this bearing support axial loads?
Yes. Its double row angular contact design enables it to support axial loads in both directions as well as radial loads.

Frequently Asked Questions from Engineers and Mechanics

Can the 3007 B 2RS replace two single row angular contact bearings?
In certain applications, a double row angular contact bearing can provide functionality similar to a matched pair of single row bearings. However, load capacity, internal clearance, rigidity and installation dimensions must be checked before substitution.

Is the 3007 B 2RS suitable for gearboxes?
Yes, provided its load capacity, speed, temperature and mounting requirements correspond to the operating conditions of the gearbox.

Should the 2RS seals be removed?
Normally, no. The seals are part of the bearing design and help protect the rolling elements and lubricant.

Why is the contact angle important?
The contact angle influences the bearing's ability to accommodate axial loads and combined loading.

Is checking the 35x62x20 dimensions enough when selecting a replacement?
No. The bearing type, sealing arrangement, contact angle, internal clearance and operating requirements should also be verified.
