61705 ZZ ZEN 25x32x4 Thin Section Deep Groove Ball Bearing

Product Overview

61705 ZZ ZEN is a compact single-row thin section deep groove ball bearing with dimensions of 25x32x4 mm. The extremely small 4 mm width and 7 mm difference between bore and outside diameter make it suitable for bearing positions with severe space restrictions. The ZZ configuration uses metal shields on both sides to protect the rolling elements while retaining lubricant inside the bearing.

Industrial Applications

ZEN 61705 ZZ is suitable for precision mechanisms, compact drives, measuring equipment, automation systems, small electric devices, instrumentation and specialized industrial machinery. Its 25 mm bore combined with a 32 mm outside diameter is particularly useful where the shaft diameter is relatively large compared with the available radial installation space.

Construction

The bearing uses a single row of balls running in deep raceway grooves. Metal shields on both sides provide non-contact protection against larger contaminants while generating less friction than contact seals. The compact 25x32x4 mm geometry enables installation in narrow bearing housings where conventional deep groove bearings cannot be accommodated.

Material

The rings and rolling elements are manufactured from bearing steel designed for repeated rolling contact. The metal shields protect the internal rolling system and help retain the factory lubricant. Bearing life depends on load, rotational speed, temperature, contamination, shaft and housing fits, alignment and installation accuracy.

Why Industrial Buyers Choose 61705 ZZ ZEN

61705 ZZ ZEN 25x32x4 is suitable for OEM replacement, maintenance stock, industrial service, machine rebuilding and production support. Its exceptionally compact cross-section solves bearing selection requirements where radial and axial installation space is limited. The ZZ shields provide integrated contamination protection without requiring an open bearing arrangement.

Operational Advantages

• 4 mm width supports extremely compact bearing arrangements.
• 25 mm bore provides a large shaft diameter relative to the bearing cross-section.
• ZZ metal shields protect the internal rolling elements on both sides.
• Deep groove geometry accommodates radial and limited axial loads.
• Shielded construction helps retain lubricant inside the bearing.
• 25x32x4 mm dimensions provide precise replacement identification.

FAQ

What are the dimensions of 61705 ZZ ZEN?

The bearing has a 25 mm bore, 32 mm outside diameter and 4 mm width.

What does ZZ mean in 61705 ZZ?

ZZ indicates metal shields on both sides of the bearing, providing protection against contamination while helping retain lubricant.

Why is 61705 considered a thin section bearing?

Its 25x32x4 mm geometry provides a very small radial cross-section and only 4 mm axial width relative to the 25 mm bore.

Can 61705 ZZ accommodate axial loads?

As a deep groove ball bearing, it can accommodate radial loads and limited axial loads in both directions, subject to the operating conditions and bearing arrangement.

Where is a 25x32x4 bearing typically used?

This dimension is particularly suitable for compact mechanisms, precision equipment and industrial assemblies where a 25 mm shaft must be supported within very limited installation space.
