2022 October 4th Week KYOCM News Recommendation - Zero-Max Introduces New OHLA Models


Zero-Max did it again – three entirely new Extra-Duty Overhung Load Adaptor (OHLA) models. Based on decades of experience solving overhung load issues in the most demanding applications, the new designs feature a number of carefully chosen upgrades including spherical bearings, enhanced sealing technology, stronger shafts and a longer profile delivering increased operating life, heavy load capacities, and higher speed ratings.

While the standard OHLA product line is designed to handle high loads at high operating speeds, these new Extra-Duty models are designed to maximize performance in the most demanding applications. They provide a solid, permanent mounting surface eliminating premature motor or pump failure due to axial and radial overhung loads on a motor or pump shaft. They feature these important design enhancements:

Extended Housing Length for improved load distribution on the bearings, increasing load capacity and operating lifetime.

Spherical Roller Bearings as standard for the best combination of high load and high-speed capacity.

Dual Grease Zerks with one grease fitting located above each spherical bearing to apply grease directly into both bearing assemblies.

Heat Treated Shafts with splined input bores as standard for handling higher torque and higher shock load applications.

O-Ring Seal at input that provides a consistent, positive seal between the hydraulic pump/motor and the Overhung Load Adaptor.

Special Bi-Directional Dual-Lip Seal at the output shaft with two primary seal lips to keep lubricant in the OHLA bearings and dirt and debris outside of the OHLA. NOTE: Typical dual lip seals have a primary lip seal for fluid separation on one side with a secondary lip for excluding contaminants on the other side. This new specially designed Extra-Duty seal has two opposing primary lip sealing surfaces to provide fluid separation and contaminant exclusion from both directions – inside and outside of the OHLA. Additionally, this newly designed seal is rubber coated with stainless steel garter springs for added corrosion protection from the external environment with enhanced protection from debris and other contaminants.

The three new Extra-Duty models are:

• 350 Series (SAE A mount, accepts 2-bolt and 4-bolt Magneto mounting patterns)

• 650 Series (SAE B mount, accepts 2-bolt and 4-bolt mounting patterns)

• 950 Series (SAE C mount, accepts 2-bolt and 4-bolt mounting patterns)

Special Extra-Duty OHLA designs are also available for applications with challenging performance, material, and dimensional specifications including vertical shaft mounting orientations. Zero-Max offers a free analysis of any overhung load application to assure proper selection including estimated bearing life, confirming strength of the input shaft connection and making lubrication recommendations. There is no engineering charge for custom designs, and they are available in any quantity from one to hundreds or thousands of units.

Cylindrical Roller Bearing:

KYOCM cylindrical roller bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life. KYOCM cylindrical roller bearings include single row cylindrical roller bearings, double row cylindrical roller bearings and four row cylindrical roller bearings.


Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.
