SKF 61944 Deep Groove Ball Bearings high temperature resistant bearings lithium grease bearing stainless steel sealed

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. 

They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. 

The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. 

Integral sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed  makes radial and axial load in both directions, so it requires little maintenance.

SKF 61944 Deep Groove Ball Bearings:

Dimensions:

Inner diameter (d): 220 mm

Outer diameter (D): 300 mm

Width (B): 38 mm

Design:

The 61944 features a single-row deep groove ball design, ideal for accommodating both radial and axial loads in both directions. 

The design is especially optimized for high-speed applications, where minimal friction and low noise are required.

Material:

Typically made from high-quality steel (often chrome steel), which ensures good durability, wear resistance, and performance in various environments.

Sealing:

Open (unsealed)

RS (rubber seals on one side)

2RS (rubber seals on both sides)

Z (metal shield on one side)

2Z (metal shields on both sides)

The type of sealing or shielding you choose will depend on the operating environment, such as whether you need protection from dust, moisture, or other contaminants.

Applications:

General Industrial Applications: Widely used in machinery where high-speed operation and low maintenance are required, 

including pumps, fans, conveyors, and gearboxes.

Heavy-duty and Large Machines: With its large dimensions (220 mm inner diameter), it’s suitable for industrial machinery, agricultural machinery, 

and other heavy-duty applications.

Automotive: Can also be used in automotive applications requiring high-speed and high-load capacity.

Performance:

The SKF 61944 is engineered to provide excellent performance in terms of load capacity, reliability, and speed. 

Its design helps reduce wear over time and can handle both radial and axial loads efficiently.

Speed: It can handle relatively high speeds for its size and is ideal for applications like motors and turbines, where precision and low friction are essential.

Load Capacity:

It has a high radial load capacity and a moderate axial load capacity in both directions. However, for applications requiring higher axial load capacity, 

a bearing with a more specialized design, such as an angular contact ball bearing, may be more appropriate.

Noise and Vibration:

As with other SKF bearings, the 61944 is designed for low noise and smooth operation. The deep groove ball design helps ensure less vibration at high speeds.

Temperature Range:

The bearings are designed to operate in a broad range of temperatures, but specific temperature limits depend on the type of lubrication and sealing used.

Key Specifications:

d (Inner Diameter): 220 mm

D (Outer Diameter): 300 mm

B (Width): 38 mm

Dynamic Load Rating (C): 490 kN

Static Load Rating (C0): 410 kN

Speed: High-speed capability

Sealing Options: Open, 2RS, Z, 2Z, depending on the application
