FAQ - Frequently Asked Questions

Q1: What does “ZZ” mean in bearing designation?
A deep groove ball bearing with “ZZ” designation has metal shields on both sides of the bearing, providing protection against contamination and helping retain lubrication.

Q2: How to select correct miniature bearing size like 6x22x7 mm?
Match the shaft diameter (6 mm), the housing bore (22 mm) and the width (7 mm) exactly. Confirm load conditions and sealing requirements. The 636 ZZ MGK fits standard metrics for miniature industrial drives.

Q3: Where are 636 series bearings commonly used?
In compact rotary systems such as small motors, gearboxes, automation modules, robotics, conveyor roll systems and measurement devices where space is constrained.

Q4: Is the sealed version maintenance-free?
Sealed (ZZ) bearings retain their lubricant and protect against contamination - often requiring no further lubricant maintenance in typical automation and industrial applications.

Q5: What does “MGK” series imply?
“MGK” denotes a quality series of bearings focused on industrial reliability, stable operation, reduced friction and extended lifespan.
