63800-2RS EZO 10x19x7 mm - Deep Groove Ball Bearing

63800-2RS EZO 10x19x7 mm - Deep Groove Ball Bearing

EZO 63800-2RS is a compact single-row deep groove ball bearing with dimensions 10x19x7 mm, fitted with seals on both sides. The 63800 series combines a 10 mm bore with a small 19 mm outside diameter, making it suitable for mechanisms with limited radial installation space. The 2RS design helps protect the bearing interior against contaminants and retain lubricant.

Technical data

EZO 63800-2RS dimensions

The basic dimensions are:

d: 10 mm
D: 19 mm
B: 7 mm

Complete dimensional specification:

10x19x7 mm

The combination of a 10 mm bore and only 19 mm outside diameter makes the 63800-2RS particularly useful where radial installation space is restricted.

What does 63800-2RS mean?

The complete designation 63800-2RS identifies both the bearing size and closure configuration.

63800 - deep groove ball bearing size with dimensions 10x19x7 mm.

2RS - seals on both sides of the bearing.

The complete designation should be checked carefully because bearings with a 10 mm bore are available in several dimensional series with different outside diameters and widths.

EZO 63800-2RS construction

EZO 63800-2RS is a single-row deep groove ball bearing. Its basic construction consists of:

• inner ring,
• outer ring,
• balls,
• cage,
• seals on both sides.

Deep raceway grooves enable the bearing to accommodate primarily radial loads. Deep groove ball bearings can also accommodate axial loads within the operating limits of this bearing type.

What does 2RS mean?

The 2RS designation indicates seals on both sides of the bearing.

This design helps to:

• reduce the ingress of contaminants,
• protect the raceways and rolling elements,
• retain lubricant inside the bearing,
• reduce maintenance requirements in typical operating conditions.

The 2RS version should not be confused with a ZZ version fitted with metal shields.

63800-2RS vs 63800ZZ

Both versions have the same basic dimensions:

10x19x7 mm

The principal difference is the closure system.

63800-2RS - seals on both sides.

63800ZZ - metal shields on both sides.

The ZZ version uses non-contact metal shields, while the 2RS version uses a different sealing system. Selection should take into account contamination, operating speed and the requirements of the particular mechanism.

63800-2RS vs 6800-2RS

These two bearing sizes should not be confused.

63800-2RS: 10x19x7 mm
6800-2RS: 10x19x5 mm

Both have a 10 mm bore and 19 mm outside diameter, but their widths are different.

The 63800-2RS is 7 mm wide, while the 6800-2RS is 5 mm wide. They should therefore not be assumed to be directly interchangeable.

Compact 10x19x7 mm bearing

EZO 63800-2RS combines:

• 10 mm bore,
• 19 mm outside diameter,
• 7 mm width.

This geometry is particularly useful in compact designs where a 10 mm shaft must be supported while the available radial installation space is limited.

Selection and interchangeability

When selecting an EZO 63800-2RS, verify:

• complete 63800-2RS designation,
• 10 mm bore diameter,
• 19 mm outside diameter,
• 7 mm width,
• seals on both sides,
• required load capacity,
• operating speed,
• environmental conditions,
• lubrication requirements,
• shaft and housing fits.

Particular attention should be paid to the 7 mm width, as other 10x19 mm bearings are available with different widths.

Applications

63800-series deep groove ball bearings are suitable for compact mechanisms where a relatively large bore is required in combination with a small outside diameter.

The suitability of EZO 63800-2RS for a specific application should be evaluated according to actual loads, rotational speed, operating environment and equipment design requirements.

Installation

Mounting force should not be transmitted through the balls and raceways.

When fitting the bearing onto a shaft, force should be applied to the inner ring. When pressing the bearing into a housing, force should be applied to the outer ring.

Direct pressure on the seals should also be avoided. Cleanliness, correct alignment and suitable shaft and housing tolerances are particularly important for compact bearings.

FAQ - EZO 63800-2RS

What are the dimensions of EZO 63800-2RS?

The bearing measures 10x19x7 mm, with a 10 mm bore, 19 mm outside diameter and 7 mm width.

What type of bearing is 63800-2RS?

It is a compact single-row deep groove ball bearing.

What does 2RS mean?

2RS indicates seals on both sides of the bearing.

Are 63800-2RS and 63800ZZ the same size?

Yes. Their basic dimensions are 10x19x7 mm, but they use different closure systems.

Is 63800-2RS the same as 6800-2RS?

No. 63800-2RS measures 10x19x7 mm, while 6800-2RS measures 10x19x5 mm.

What is the difference between 63800-2RS and 6800-2RS?
