Needle bearings 1.5mm are precision components that play a crucial role in various industrial applications, from automotive transmissions to textile machinery. Their compact size, low friction, and high load capacity make them ideal for situations where space is limited and high performance is required. This article provides a comprehensive overview of needle bearings 1.5mm, including their design, types, specifications, and applications.
Needle bearings 1.5mm consist of cylindrical rollers (needles) that are precisely guided within a thin-walled outer race. The needles are typically made of high-grade steel, hardened and ground to ensure smooth operation and long service life. The outer race is usually made of hardened steel or bearing-grade plastic.
The needles are arranged in a radial or axial configuration, depending on the application. Radial needle bearings support loads perpendicular to the bearing axis, while axial needle bearings support loads parallel to the bearing axis.
Needle bearings 1.5mm are available in various types to suit different application requirements. The most common types include:
Needle bearings 1.5mm are characterized by their precise dimensions and performance specifications. The following table lists the key specifications for commonly used needle bearings 1.5mm:
Specification | Value |
---|---|
Inner diameter | 1.5mm |
Outer diameter | 3mm, 4mm, 5mm |
Length | 1.5mm, 2mm, 3mm |
Number of needles | 12, 16, 20 |
Load capacity | 35N to 80N |
Operating speed | 10,000 to 20,000 rpm |
Operating temperature | -20°C to 120°C |
