About

Roviatech is a Korean company based in Seoul, South Korea, working with bearings. The Roviatech Blog shares what we have learned from more than 30 years in the bearing trade, written for the people who actually choose, buy and replace bearings.

Who it is for

• Maintenance engineers who keep machines running
• Buyers who source bearings and spare parts
• Students learning about machine elements

What we write about

• Questions from the field — noisy or hot bearings, finding equivalents across brands, and sourcing discontinued bearings.
• Bearing basics — how to read bearing numbers, how to choose a bearing type, and bearing life and lubrication, explained without heavy math.
• Where bearings work — wind turbines, robots, semiconductor plants and more.

Written in Korea

We work with bearings every day in Korea's machinery market and write from that experience. Most articles are published in Korean first, and selected articles are translated into English.
