PFI PC35480020CS 35x48x20 Double Row Angular Contact Ball Bearing

PFI PC35480020CS 35x48x20 Double Row Angular Contact Ball Bearing

PFI PC35480020CS is a double-row angular contact ball bearing with nominal dimensions of 35x48x20 mm, intended for automotive air-conditioning compressor applications. The verified principal dimensions are d = 35 mm, D = 48 mm and T = 20 mm. Product listings associate this bearing with compressor systems including Sanden TRSA09, TRSA12, TRSE07 and Delphi.

PFI PC35480020CS - Technical Characteristics

Verified identification data:

Brand: PFI

Designation: PC35480020CS

Alternative notation: PC 35480020 CS

Product type: Double-row angular contact ball bearing

Application category: Automotive A/C compressor bearing

Bore diameter d: 35 mm

Outside diameter D: 48 mm

Total width T: 20 mm

Dimensions: 35x48x20 mm

The key product identification is:

PFI + PC35480020CS + 35x48x20 mm + double-row angular contact ball bearing

This complete combination should be retained when identifying the bearing.

PFI PC35480020CS Dimensions

The principal dimensions are:

d = 35 mm - bore diameter

D = 48 mm - outside diameter

T = 20 mm - total width

Complete dimensions:

35x48x20 mm

The unusually compact 48 mm outside diameter with a 35 mm bore is an important identification feature of this bearing.

Dimensions alone, however, should not be treated as sufficient proof of interchangeability.

Double-Row Angular Contact Ball Bearing Design

PFI PC35480020CS is identified as a:

Double-Row Angular Contact Ball Bearing

A double-row angular contact arrangement uses two rows of balls and corresponding raceway geometry.

Compared with a conventional single-row radial ball bearing, this construction is intended to accommodate combined loading and provides axial load capability in both directions within a compact bearing arrangement.

This construction is particularly relevant in applications where the bearing must locate a rotating component while operating under both radial and axial forces.

The exact contact angle and internal geometry of PFI PC35480020CS have not been confirmed from manufacturer technical documentation and are therefore not assigned here.

A/C Compressor Bearing Application

PFI PC35480020CS is catalogued specifically as an automotive air-conditioning compressor bearing.

Available application data identify compressor systems including:

Sanden TRSA09

Sanden TRSA12

Sanden TRSE07

Delphi compressor applications

In this type of application, the bearing is associated with the compressor pulley arrangement.

Application information should be used together with the original bearing designation and dimensions rather than as the sole basis for selection.

PC35480020CS Designation

The dimensional part of the designation corresponds directly with the bearing size:

35 - 35 mm bore

48 - 48 mm outside diameter

0020 / 20 - 20 mm width

The complete PFI reference is:

PC35480020CS

The suffix CS forms part of the PFI commercial designation and should be retained when ordering.

Its detailed manufacturer-specific technical meaning should not be expanded without an authoritative PFI designation table.

PFI PC35480020CS vs PC35480020

The product can be encountered in searches and catalogues in shortened forms such as:

PC35480020

PC 35480020

However, PFI product listings identify the complete reference as:

PC35480020CS

For accurate ordering and product identification, the full PFI designation should be preferred.

PFI PC35480020CS and NSK 35BD4820AT1

Available cross-reference data associate:

PFI PC35480020CS

with:

NSK 35BD4820AT1

Both references are associated with the 35x48x20 mm A/C compressor bearing application.

This cross-reference is useful for identification, but replacement should still be based on the complete bearing specification, compressor application and original bearing reference.

A cross-reference does not by itself establish universal interchangeability in every installation.

Selection and Interchangeability

Before replacing PFI PC35480020CS, verify:

PFI designation PC35480020CS

d = 35 mm

D = 48 mm

T = 20 mm

Double-row angular contact construction

Sealing configuration

Compressor manufacturer and model

Original bearing designation

Pulley and compressor installation dimensions

A conventional bearing measuring 35x48x20 mm should not automatically be treated as an equivalent.

The internal construction and intended compressor application must also be compatible.

FAQ

What are the dimensions of PFI PC35480020CS?

The bearing measures 35x48x20 mm: bore diameter 35 mm, outside diameter 48 mm and total width 20 mm.

What type of bearing is PC35480020CS?

It is a double-row angular contact ball bearing intended for automotive A/C compressor applications.

Is PC35480020CS an A/C compressor bearing?

Yes. It is catalogued as a bearing for automotive air-conditioning compressor applications.

Which compressors use PC35480020CS?

Available application data include Sanden TRSA09, TRSA12, TRSE07 and Delphi compressor systems.

What is the NSK cross-reference for PC35480020CS?

Available cross-reference data identify NSK 35BD4820AT1.

Is PC35480020 the same designation as PC35480020CS?

PC35480020 is frequently used as a shortened reference, but the complete PFI designation found in product catalogues is PC35480020CS.

Can any 35x48x20 bearing replace PC35480020CS?

No. The dimensions alone are insufficient. The double-row angular contact construction, sealing arrangement and compressor application must also be verified.

What does CS mean in PC35480020CS?

CS is part of the complete PFI product designation. Its exact manufacturer-specific meaning should not be inferred without an authoritative PFI designation table.

Engineer FAQ

Why is a double-row angular contact bearing used in an A/C compressor pulley?

A double-row angular contact arrangement provides a compact bearing configuration capable of supporting combined radial and axial loading and axial forces in both directions.

Is the contact angle known for PC35480020CS?

No verified PFI-specific contact angle has been found, so a numerical contact angle should not be assigned to this bearing.

Are C and C0 load ratings available?

No sufficiently authoritative PFI-specific dynamic and static load ratings have been confirmed for this exact reference. Values from NSK or another dimensionally equivalent bearing should not be transferred to PFI.

Should compressor application be checked even if the old bearing measures 35x48x20 mm?

Yes. Dimensions, bearing construction, original reference and compressor/pulley configuration should all be checked.

Is NSK 35BD4820AT1 automatically interchangeable with PFI PC35480020CS?

It is a documented cross-reference in available A/C compressor bearing catalogues, but final interchangeability should be confirmed against the original compressor and bearing specification.
