61911 2RS ZVL 55x80x13 Deep Groove Ball Bearing

What Is the 61911 2RS ZVL Bearing?

61911 2RS ZVL is a single-row deep groove ball bearing with dimensions 55x80x13 mm. It belongs to the compact 619 dimensional series and is designed primarily for radial loads while also accommodating axial loads in both directions. The 2RS design features seals on both sides, helping retain lubricant inside the bearing and protect the rolling elements against dust, dirt and other contaminants.

What Does 61911 2RS Mean?

The designation identifies the bearing's basic design and sealing arrangement:

• 61911 - deep groove ball bearing from the compact 619 series
• 2RS - seals on both sides of the bearing
• ZVL - bearing manufacturer
• 55x80x13 - bore, outside diameter and width

The compact cross-section makes the 619 series particularly useful where installation space is limited.

2RS Sealing Design

The 2RS seals protect both sides of the bearing and help keep lubricant inside the rolling element area.

This design provides several practical benefits:

• Protection against dust and dirt
• Reduced contamination of the rolling elements
• Lubricant retention
• Reduced maintenance requirements
• Improved reliability in demanding environments

Compared with an open bearing, the sealed version is particularly useful in applications where external contamination may reach the bearing arrangement.

Compact 619 Series Design

A characteristic feature of the 61911 is its relatively thin cross-section. Despite having a 55 mm bore, the outside diameter is only 80 mm, while the width is 13 mm.

This makes the bearing suitable for equipment where radial and axial installation space is restricted.

Typical examples include compact drive units, electric motors, mechanical assemblies and specialized industrial machinery.

Radial and Axial Loads

As a deep groove ball bearing, the 61911 2RS ZVL is primarily designed to carry radial loads.

The deep raceway geometry also allows the bearing to accommodate axial loads in both directions. This makes the design suitable for many applications where combined loading occurs.

When selecting the bearing, consider:

• Radial load
• Axial load
• Rotational speed
• Operating temperature
• Required internal clearance
• Shaft and housing fits
• Environmental conditions

Typical Applications

The 61911 2RS ZVL 55x80x13 can be used in:

• Electric motors
• Industrial pumps
• Gear drives
• Fans
• Industrial machinery
• Automation equipment
• Production machinery
• Agricultural equipment
• Conveyor systems
• Mechanical assemblies
• Maintenance and repair applications

Advantages of the 61911 2RS ZVL

Key operational advantages include:

• Compact 55x80x13 mm dimensions
• Sealing on both sides
• Radial load carrying capability
• Axial load capability in both directions
• Efficient lubricant retention
• Protection against contamination
• Low-friction rolling operation
• Wide range of industrial applications

Installation Recommendations

Before installation, verify:

• Shaft diameter of 55 mm
• Housing bore of 80 mm
• Required shaft and housing tolerances
• Alignment of the shaft and housing
• Condition of mounting surfaces
• Required internal clearance
• Operating load and speed

During press fitting, force should be applied only to the bearing ring being mounted with an interference fit. Installation force should never be transmitted through the balls and raceways.

Frequently Asked Questions (FAQ)

What are the dimensions of the 61911 2RS ZVL?
The bearing has a 55 mm inside diameter, 80 mm outside diameter and 13 mm width.

What does 2RS mean?
2RS indicates that the bearing is equipped with seals on both sides.

Is the 61911 2RS a single-row bearing?
Yes. It is a single-row deep groove ball bearing.

Can this bearing support axial loads?
Yes. In addition to radial loads, deep groove ball bearings can accommodate axial loads in both directions within their design limits.

Why is the 61911 bearing relatively thin?
The 619 series is designed with a compact cross-section, making it suitable for applications with restricted installation space.

Frequently Asked Questions from Engineers and Mechanics

Can the 61911 2RS ZVL be replaced by another brand?
Potentially yes, provided the dimensions, bearing design, sealing arrangement, internal clearance, load ratings and operating requirements are equivalent.

Does a 2RS bearing require additional lubrication before installation?
Normally no. Sealed bearings are typically supplied with grease inside and are intended to retain that lubricant during operation.

Should the 2RS seals be removed?
Normally not. The seals are an integral part of this bearing version and protect the internal components against contamination.

Is checking the 55x80x13 dimensions enough?
No. When selecting a replacement, also verify the sealing type, internal clearance, load capacity, speed capability and requirements of the specific machine.

Where is the 61911 2RS commonly used?
It can be found in electric motors, pumps, compact drive systems, industrial machinery, automation equipment and other mechanical assemblies.
