Inch Series Angular Contact Spherical Plain Bearings
Steel-on-Steel | Inch Series | Open Type | Relubricatable
GACZ…S Angular Contact Spherical Plain Bearings are inch-series, steel-on-steel spherical plain bearings designed to accommodate combined radial and axial loads while allowing angular movement and misalignment.
Unlike radial spherical plain bearings, the GACZ…S series features inclined spherical sliding contact surfaces. This angular contact design enables the bearing to support axial loads acting in one direction together with radial loads.
The bearing consists of an inner ring with a convex spherical sliding surface and an outer ring with a matching concave spherical sliding surface. The rings are typically manufactured from hardened bearing steel to provide load-carrying capability and resistance to wear.
The sliding surfaces may be phosphated and treated with molybdenum disulfide (MoS₂) to help reduce friction. The outer ring incorporates lubrication grooves and holes to facilitate grease distribution and periodic relubrication.
GACZ…S bearings are suitable for industrial applications requiring combined load support, angular movement, and regular maintenance.
The inclined spherical sliding surfaces enable GACZ…S bearings to accommodate combined radial and axial loads.
A single bearing supports axial loading in one direction. For applications requiring axial load support in both directions, two bearings can be installed in an opposed arrangement.
GACZ…S bearings feature inch-based dimensions, making them suitable for machinery and equipment designed according to imperial bearing specifications.
The inner and outer rings are typically manufactured from hardened bearing steel, such as 52100 or equivalent GCr15 bearing steel.
This construction provides load-carrying capability for industrial applications involving substantial mechanical loads.
Depending on the manufacturer's specification, the bearing rings may receive protective surface treatments.
Phosphating and molybdenum disulfide (MoS₂) treatment can help reduce sliding friction and provide surface protection.
GACZ…S bearings are maintenance-required bearings.
The outer ring incorporates lubrication grooves and holes to allow grease replenishment.
Certain designs also feature crossed lubrication grooves on the loaded sliding surface to help distribute grease more effectively.
The spherical sliding contact design accommodates angular movement and limited misalignment between connected components.
The permissible misalignment angle varies according to bearing size and installation conditions.
GACZ…S bearings are generally supplied in an open configuration without integral contact seals.
Appropriate lubrication and protection against contamination should be considered during installation and operation.

GACZ…S Angular Contact Spherical Plain Bearings can be considered for various industrial applications, including:
Hydraulic cylinders and actuator connections
Construction and earthmoving machinery
Agricultural equipment
Industrial lifting and handling equipment
Heavy-duty mechanical linkages
Mining and material handling machinery
Articulated mechanical assemblies
Industrial equipment subjected to combined radial and axial loads
The suitability of each bearing depends on the actual operating conditions, load direction, lubrication requirements, and mounting arrangement.
GACZ…S bearings feature steel-on-steel sliding contact surfaces and require proper lubrication.
The lubrication grooves and holes in the outer ring allow grease to reach the sliding contact surfaces.
Regular relubrication helps reduce friction and wear during operation.
The lubrication interval should be determined according to operating loads, movement frequency, temperature, environmental conditions, and lubricant characteristics.
When selecting GACZ…S Angular Contact Spherical Plain Bearings, the following factors should be considered:
Bore diameter and outside diameter
Inner and outer ring widths
Radial and axial load requirements
Direction of axial loading
Dynamic and static load ratings
Permissible misalignment angle
Lubrication and maintenance conditions
Operating temperature and environment
For applications involving axial loads in both directions, an opposed bearing arrangement should be evaluated.
