What is SVC treatment? Explanation of TNK's original heat treatment!

SVC treatment is a proprietary welding technology from TNK (Sanwa Needle Bearing Co., Ltd.). By using SVC treatment, we can create high-hardness, non-magnetic products. In this article, we will explain our proprietary welding technology, SVC treatment, from its characteristics to the materials it can be used on.

Technology introduction

Prototype production possible from as little as one piece

TNK (Sanwa Needle Bearing Co., Ltd.) has a prototype department within its technical department, with a total of more than 20 engineers. With their wealth of knowledge and experience, they can carefully listen to customers' requests and then create the appropriate prototype for their application.

Technology introduction

What is carburizing? Processing methods, types, benefits, and more explained!

Carburizing is a heat treatment technique that is mainly used to increase the surface hardness of low carbon steel and improve its wear resistance. The treatment increases the carbon concentration on the metal surface, and the surface is hardened by subsequent quenching and tempering. This treatment gives the surface a high hardness and […]

Technology introduction

What is TNK heat treatment? Explaining the processing methods, types, benefits, and more!

Heat treatment is carried out to improve hardness, strength, and wear resistance, as well as to remove internal stress. It is used in a wide range of products, primarily automotive and machine parts, and is also available at Sanwa Needle Bearings. In this article, we will introduce the heat treatment technology we offer.

Technology introduction

The pursuit of ultra-high precision

Sanwa Needle Bearing's strength is its expertise in ultra-precision grinding with submicron (1/10000 mm) accuracy. By refining centerless grinding as its core technology, the company is able to mass-produce bearings with an outer diameter accuracy of ±0.0001 mm, something no other company can match.

Technology introduction

What is our commitment to quality?

One of the most important elements in manufacturing is a reliable quality control system. We have built a thorough quality control system based on a strong sense of mission that "we cannot tolerate even one defective product in a million." For this reason, we continue to focus on the precision of our products and produce products in Japan.

Technology introduction

What is a flexible production system?

Except for special products, we have a system in place that allows us to basically carry out all production in-house. In particular, by completing the heat treatment process, which other companies tend to outsource, in-house, we are able to achieve stable quality, improve cost performance, and meet the needs of our customers.
