Heavy Duty Needle Roller Bearings (Machined)

Overview of Heavy Duty Needle Roller Bearings (Machined)

Machined Type Heavy Duty Needle Roller Bearings are specifically engineered for applications involving heavy radial loads. These bearings have a low sectional height while offering high load ratings, making them ideal for installations where space is limited but strength is critical.

Key Features

• High Load Capacity: Thanks to their needle roller design and precision-machined outer rings, these bearings can handle substantial radial loads.
• Compact Structure: The low-profile design allows for compact assembly, which is particularly beneficial in applications with space constraints.
• High Rigidity: The outer ring is designed with excellent structural rigidity, making it compatible even with lightweight alloy housings.

Design Variants

These bearings are available in both metric and inch series, offering flexibility for global applications. They are manufactured in two main types:

• Caged type: Incorporates a cage to maintain needle roller spacing, reducing friction and heat generation, suitable for higher-speed applications.
• Full complement type: Contains a full set of needle rollers without a cage, maximizing load capacity, ideal for slower speeds and oscillating motions.

Inner Ring Options

Machined needle roller bearings are available with or without inner rings:

• With inner ring: Provides a complete bearing unit, simplifying mounting and improving wear resistance on shafts that are not hardened or ground.
• Without inner ring: Utilizes the shaft itself as the raceway, enabling a more compact design and reducing the overall bearing assembly size.

Applications

These bearings are ideal for use in construction equipment, automotive transmissions, gearboxes, agricultural machinery, and other heavy-duty industrial environments where space-saving and high load capacity are essential.

Interchangeability

Heavy duty machined needle roller bearings are interchangeable with products from leading manufacturers such as Schaeffler (INA), ensuring compatibility and ease of sourcing.

Why Choose These Bearings?

Their exceptional durability, precision-machined outer rings, and ability to operate under demanding conditions make them a reliable choice for engineers and maintenance professionals. Whether your application involves continuous rotation at high speeds or slower oscillating movements under heavy loads, these bearings deliver consistent performance and long service life.
