Among the different sizes available, needle bearing 1.5mm is commonly used in applications requiring high precision and compact design. This guide delves into the world of needle bearings 1.5mm, exploring their advantages, applications, and practical considerations.
Needle bearings 1.5mm offer several advantages that make them suitable for demanding applications. These benefits include:
Applications of Needle Bearings 1.5mm
Due to their versatility and benefits, needle bearings 1.5mm find applications in a wide range of industries, including:
Needle bearings 1.5mm consist of a cylindrical outer ring, an inner ring, and a set of needle rollers. The needle rollers, which have a high length-to-diameter ratio, are arranged radially between the two rings.
When the bearing rotates, the needle rollers make rolling contact with the inner and outer rings, reducing friction and allowing for smooth, precise movement.
Factors to Consider When Choosing Needle Bearings 1.5mm
When selecting needle bearings 1.5mm, several factors should be considered:
Outer Diameter (mm) | Inner Diameter (mm) | Width (mm) | Load Capacity (N)* |
---|---|---|---|
3 | 1.5 | 1 | 100 |
4 | 1.5 | 1.5 | 150 |
5 | 1.5 | 2 | 200 |
6 | 1.5 | 2.5 | 250 |
7 | 1.5 | 3 | 300 |
*Note: Load capacities are approximate and may vary depending on bearing type and operating conditions.
