needle bearing for tvs tricycle india

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Needle bearings for TVS tricycles in India are specialized components designed to reduce friction in the rotating parts of these vehicles, particularly in applications where high load capacity and compact design are required. Here's a detailed introduction:

1. What is a Needle Bearing:

• A needle bearing is a type of roller bearing that uses long, thin cylindrical rollers resembling needles. These rollers are at least four times longer than their diameter, which distinguishes them from traditional ball bearings or shorter roller bearings. Needle bearings have a larger surface area in contact with the races, allowing them to support greater loads while being thinner and requiring less clearance between the axle and the surrounding structure .

2. Construction:

• The typical structure of a needle roller bearing includes an inner race (or sometimes just a shaft), a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer raceway. There are various designs of needle roller bearings, including drawn cup, precision race, caged roller, and thrust roller types. Caged designs come in single and double-row configurations, with cage materials such as steel, plastic (PA66), and aluminum available .

3. Applications in TVS Tricycles:

• Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. For TVS tricycles, these bearings are crucial in drive shafts, where they help to reduce friction and support the weight of the vehicle, especially in the rear-wheel drive setup. A rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint), and this number can increase if the drive shaft is particularly long or operates on steep slopes .

4. Manufacturers in India:

• Companies like SNL Bearings Limited are leading manufacturers of needle roller bearings primarily for the automobile industry, including TVS tricycles. They have been supplying to major automobile manufacturers like BAJAJ, LML, KINETIC ENGG.TVS, MARUTI, and TATA MOTORS for over two decades. SNL Bearings Limited is known for its world-class technology and machines in needle bearing manufacturing, with a focus on cost-effective manufacturing and low-cost automation .

5. Technical Specifications:

• Engineers must consider various factors when selecting needle roller bearings for TVS tricycles, including the size/design envelope, type of load, load capacity, speed, temperature, misalignment, housing and shaft specifications, service life, and lubrication requirements .

6. Advantages:

• Needle bearings offer several advantages, such as high load capacity, thin profile, and low friction. They are also known for their precision and durability, making them ideal for use in tricycles where reliability and performance are critical.

In summary, needle bearings play a vital role in the performance and longevity of TVS tricycles in India, providing efficient load support and reduced friction in critical components such as drive shafts and transmissions.
