HK 1012 MTM - Needle Roller Bearing 10x14x12

Applications - Compact Bearing Solution for Industrial Systems

The HK 1012 MTM is a thin-walled needle roller bearing designed for compact mechanical assemblies where high radial load capacity is required within limited installation space. With dimensions 10x14x12 mm, this bearing is commonly used in gearboxes, electric drives, agricultural machinery, automation equipment, and light industrial systems.

Thanks to its compact outer diameter and optimized internal geometry, the HK 1012 MTM can be installed directly into a properly machined bearing housing, forming an efficient and space-saving bearing unit. It is particularly suitable for applications where a standard ball bearing would not provide sufficient radial load capacity within the same dimensions.

Design Advantages - High Durability and Load Capacity

Unlike a traditional ball bearing, a needle roller bearing uses multiple slender cylindrical rollers. This design increases the contact surface area and allows the bearing to support higher radial loads relative to its size.

The hardened outer ring ensures structural rigidity and dimensional stability during operation. When combined with a properly hardened shaft acting as the inner raceway, the bearing delivers high durability and consistent performance under dynamic industrial conditions.

The HK 1012 MTM is engineered for radial loads and is ideal for rotating components operating at moderate speeds. Its thin-walled construction enables lightweight and compact mechanical designs without compromising performance.

FAQ - Frequently Asked Questions

What is the difference between a needle roller bearing and a ball bearing?
A needle roller bearing uses cylindrical rollers instead of balls, providing higher radial load capacity in a smaller cross-section.

Does HK 1012 MTM require an inner ring?
In many applications, the shaft itself serves as the inner raceway, provided it meets hardness and surface finish requirements.

Where is HK 1012 commonly used?
It is used in gearboxes, industrial machinery, electric motors, and compact drive systems.

How do I select the correct bearing size?
Match the inner diameter (10 mm), outer diameter (14 mm), and width (12 mm) to the shaft and housing dimensions, considering load requirements.
