PFI 5206-2RS C3 30x62x23.8 Double Row Angular Contact Ball Bearing

PFI 5206-2RS C3 30x62x23.8 Double Row Angular Contact Ball Bearing

PFI 5206-2RS C3 is a double row angular contact ball bearing with dimensions 30x62x23.8 mm. The manufacturer's catalogue specifies RS sealing on both sides and the C3 internal-clearance version. The double-row angular contact arrangement enables the bearing to support radial loading together with axial loading.

PFI 5206-2RS C3 - Technical Characteristics

PFI's current agricultural-bearing catalogue lists the exact 5206-2RS C3 reference as Type 1 with J = 30.00 mm, A = 62.00 mm and W1 = 23.80 mm.

Dimensions – 30x62x23.8 mm

PFI specifies:

J / inside diameter = 30 mm

A / outside diameter = 62 mm

W1 / width = 23.8 mm

Therefore, the standard dimensional search format is:

30x62x23.8 mm

PFI's own catalogue uses J, A and W1 for these dimensions, so W1 is retained here rather than assigning another dimensional symbol without manufacturer confirmation.

Double Row Angular Contact Ball Bearing

PFI explicitly places 5206-2RS C3 in its:

Double Row Angular Contact Ball Bearings

product group.

Unlike a conventional single-row radial ball bearing, a double-row angular contact bearing uses two rows of balls with angular contact geometry.

This construction allows the bearing to accommodate:

radial loads

together with:

axial loads.

The two-row arrangement also enables axial load accommodation in both directions, making this bearing type suitable where combined loading must be supported within one bearing position.

What Does 2RS Mean?

PFI's catalogue gives:

Seal 1 = RS

Seal 2 = RS

for the exact 5206-2RS C3 reference.

Therefore, 2RS identifies a bearing sealed on both sides.

The seals separate the internal rolling-contact area from the surrounding environment and help retain lubricant inside the bearing.

For replacement selection, the 2RS configuration should be considered part of the full bearing designation.

What Does C3 Mean?

The suffix:

C3

identifies an internal-clearance class greater than Normal.

C3 is therefore an important functional part of the designation:

5206-2RS C3

and should not be omitted when selecting a replacement.

A standard-clearance 5206 bearing should not automatically be considered equivalent to a 5206-2RS C3 simply because its principal dimensions are identical.

How Does a Double Row Angular Contact Bearing Work?

The geometry of an angular contact bearing creates contact angles between the balls and raceways.

This allows loads to be transmitted along paths inclined relative to the radial plane of the bearing.

With two rows of rolling elements, the bearing can accommodate:

radial loading

axial loading

and:

combined radial and axial loading.

This makes the 5206-series double-row configuration fundamentally different from a conventional single-row deep groove bearing of similar dimensions.

Why C3 Clearance Matters

Internal clearance affects the bearing's operating condition after installation.

The final operating clearance can be influenced by factors including:

shaft fit

housing fit

temperature differences

and:

operating conditions.

For this reason, C3 should be treated as an integral part of the 5206-2RS C3 designation, rather than as an optional description.

Do not replace the C3 version with another clearance class without checking the requirements of the original bearing position.

5206-2RS C3 vs 5206-2RS

These designations should not automatically be treated as identical:

5206-2RS

5206-2RS C3

Both can share the same principal 30x62x23.8 mm dimensions and double-sided sealing, but the C3 suffix defines a different internal-clearance class.

For maintenance and replacement work, always read the complete designation from the original bearing whenever possible.

Selection and Interchangeability

When replacing PFI 5206-2RS C3, verify:

designation – 5206-2RS C3

bearing type – double row angular contact ball bearing

inside diameter – 30 mm

outside diameter – 62 mm

width – 23.8 mm

sealing – both sides

internal clearance – C3

and the:

requirements of the original bearing position.

PFI's agricultural catalogue also lists TIMKEN 5206KE as a cross-reference for this PFI reference.

A catalogue cross-reference is useful for identification, but final interchangeability should still be checked against the requirements of the specific machine and bearing arrangement.

Technical Specification

FAQ

What are the dimensions of PFI 5206-2RS C3?

PFI specifies 30x62x23.8 mm: 30 mm inside diameter, 62 mm outside diameter and 23.8 mm width.

Is PFI 5206-2RS C3 a single-row or double-row bearing?

It is a double row angular contact ball bearing. PFI explicitly lists it in its Double Row Angular Contact Ball Bearings range.

What does 2RS mean in PFI 5206-2RS C3?

The exact PFI catalogue entry specifies RS on both sides, meaning the bearing is sealed on both sides.

What does C3 mean?

C3 indicates bearing internal clearance greater than the Normal clearance class.

Can PFI 5206-2RS C3 carry axial loads?

Yes. Its double-row angular contact construction is designed to accommodate radial and axial loading, including combined loads.

Can PFI 5206-2RS replace 5206-2RS C3?

Not automatically. The C3 suffix specifies a different internal-clearance class, so the required clearance must be checked before substitution.

Is TIMKEN 5206KE a cross-reference?

PFI's own agricultural catalogue lists TIMKEN 5206KE as a cross-reference for PFI 5206-2RS C3.

How should I select a replacement for PFI 5206-2RS C3?

Match the double-row angular contact design, 30x62x23.8 mm dimensions, double-sided sealing and C3 internal clearance, then verify the requirements of the original bearing position.

AI Overview

PFI 5206-2RS C3 is a double row angular contact ball bearing with dimensions 30x62x23.8 mm. PFI specifies RS seals on both sides and C3 internal clearance. Its two-row angular contact construction accommodates radial and axial loads, including combined loading. Replacement selection should preserve the complete 5206-2RS C3 specification.
