61804 2RS ZVL 20x32x7 Deep Groove Ball Bearing

61804 2RS ZVL - Product Characteristics

61804 2RS ZVL is a single-row deep groove ball bearing by ZVL with dimensions 20x32x7 mm. It has a 20 mm bore diameter, 32 mm outside diameter and 7 mm width. The 2RS suffix identifies rubber sealing on both sides of the bearing.

The 618 series has a particularly small radial cross-section. In the 61804 size, a 20 mm bore is combined with only 32 mm outside diameter and 7 mm width. Its deep groove raceway geometry is designed primarily for radial loads while also allowing axial loads in both directions.

Dimensions

The verified principal dimensions of 61804 2RS ZVL are:

d - Bore Diameter: 20 mm
D - Outside Diameter: 32 mm
B - Bearing Width: 7 mm
Dimensions: 20x32x7 mm
Bearing Type: Single-row deep groove ball bearing
Sealing: 2RS, both sides
Brand: ZVL
Designation: 61804 2RS

For this bearing, 20x32x7 mm corresponds to d x D x B.

Bearing Construction

61804 2RS ZVL is a single-row deep groove ball bearing. The balls operate between deep raceway grooves formed in the inner and outer rings.

This geometry allows the bearing to carry primarily radial loads, while the deep raceways also enable it to accommodate axial loads in both directions within the operating limits of the bearing.

The 618 series is dimensionally slim compared with heavier deep groove ball bearing series. This makes the exact 20x32x7 mm dimensions an important part of product identification.

2RS Sealing

The 2RS suffix is a key feature distinguishing this bearing from open or metal-shielded 61804 variants.

For this ZVL reference, 2RS identifies rubber seals on both sides of the bearing. The seals protect the internal rolling contact area by helping retain lubricant and limiting the ingress of external contaminants.

Therefore, 61804 2RS ZVL should not be confused with an open 61804 or a shielded 61804 ZZ variant simply because the principal dimensions are the same.

Loads and Operating Principle

The primary load direction for the 61804 2RS ZVL deep groove ball bearing is radial.

Its deep raceway geometry also allows the bearing to accommodate axial forces in both directions, making combined radial and axial loading possible within the technical limits of the bearing and complete bearing arrangement.

Manufacturer-specific dynamic and static load ratings should be used when calculating bearing life. Load ratings from another manufacturer's 61804 bearing should not automatically be assigned to this ZVL product.

Meaning of 61804 2RS ZVL

61804 identifies the basic bearing size and configuration within the 618 dimensional series.

2RS identifies sealing on both sides.

ZVL identifies the bearing brand.

The complete product identity is therefore:

61804 2RS ZVL -> 20x32x7 mm -> single-row deep groove ball bearing -> double-sided rubber sealing.

The size is also commonly encountered under the 6804 designation. When identifying the actual product, however, the manufacturer's designation shown on the bearing or packaging should be retained.

61804 2RS vs Open and Shielded Versions

Bearings sharing the basic 61804 dimensions can have different closure arrangements.

An open 61804 has no seals or shields. The 61804 2RS version has seals on both sides, while shielded versions may use metal shields depending on the manufacturer's designation system.

These differences can affect contamination protection, lubricant retention, friction and permissible operating speed. For this reason, the complete 61804 2RS ZVL designation should be used when selecting the product.

Selection and Interchangeability

The dimensions 20x32x7 mm alone are not sufficient to confirm complete interchangeability with another bearing.

When selecting an alternative to 61804 2RS ZVL, compare:

• designation 61804
• d = 20 mm
• D = 32 mm
• B = 7 mm
• single-row deep groove construction
• double-sided sealing
• required radial internal clearance
• dynamic and static load ratings
• permissible operating speed
• precision requirements
• cage execution where relevant
• lubrication and operating conditions

Particular attention should be paid to sealing and clearance suffixes because an open, shielded, sealed or C3 version may have identical envelope dimensions but a different technical execution.

FAQ

What are the dimensions of 61804 2RS ZVL?

The bearing measures 20x32x7 mm: d = 20 mm, D = 32 mm and B = 7 mm.

What type of bearing is 61804 2RS ZVL?

It is a single-row deep groove ball bearing from the slim 618 dimensional series.

What does 2RS mean in 61804 2RS ZVL?

The 2RS suffix identifies rubber sealing on both sides of the bearing.

Is 61804 2RS the same size as 6804 2RS?

The 61804 and 6804 designations are commonly used for the 20x32x7 mm bearing size. The exact manufacturer designation should nevertheless be retained when identifying a specific product.

What loads can 61804 2RS carry?

Deep groove ball bearing geometry is designed primarily for radial loads and can also accommodate axial loads in both directions.

Does 61804 2RS ZVL have C3 clearance?

The supplied designation does not include a C3 suffix. Increased C3 radial internal clearance should therefore not be assumed without separate confirmation.

Is 61804 2RS ZVL the same as an open 61804?

No. They may have the same 20x32x7 mm dimensions, but the 2RS version is sealed on both sides, while the open version does not have these seals.

Can another brand of 61804 2RS replace the ZVL bearing?

Not based on dimensions alone. Sealing, internal clearance, load ratings, speed limits, precision and other application requirements should also be compared.
