SKF 6007-2RZTN9/HC5C3WT 35x62x14 Hybrid Deep Groove Ball Bearing

SKF 6007-2RZTN9/HC5C3WT is a hybrid single-row deep groove ball bearing measuring 35x62x14 mm. Its rings are manufactured from bearing steel, while the rolling elements are made from bearing-grade silicon nitride (Si3N4). This exact configuration combines 2RZ non-contact seals, TN9 polyamide cage, HC5 hybrid construction, C3 radial internal clearance and WT grease.

SKF 6007-2RZTN9/HC5C3WT - Product Characteristics

The defining feature of SKF 6007-2RZTN9/HC5C3WT is its hybrid construction. Unlike a conventional all-steel 6007 bearing, it combines bearing-steel rings with ceramic silicon nitride rolling elements.

SKF states that silicon nitride rolling elements make its hybrid bearings electrically insulating, protecting the bearing against damage caused by electric current. SKF also identifies advantages of hybrid construction including higher speed capability, high wear resistance, high bearing stiffness and reduced sensitivity to temperature gradients compared with equivalent all-steel bearings.

Dimensions

The principal dimensions of SKF 6007-2RZTN9/HC5C3WT are:

d - Bore Diameter: 35 mm
D - Outside Diameter: 62 mm
B - Width: 14 mm
Dimensions: 35x62x14 mm.

For this deep groove ball bearing, the dimensional sequence 35x62x14 mm corresponds to d x D x B.

Although these dimensions correspond to the 6007 envelope, dimensional compatibility alone does not make a standard 6007 technically identical to this bearing. The HC5, 2RZ, TN9, C3 and WT specifications are integral parts of the exact configuration.

Hybrid Bearing Construction - HC5

The HC5 component of the designation is critical to identifying this bearing.

SKF hybrid bearings combine bearing-steel rings with bearing-grade silicon nitride Si3N4 rolling elements. SKF's technical documentation explicitly identifies Si3N4 as the rolling-element material in this hybrid bearing family.

In SKF 6007-2RZTN9/HC5C3WT, the ceramic components are therefore the balls, not the bearing rings.

This means the product should correctly be described as a:

hybrid ceramic deep groove ball bearing

rather than as an entirely ceramic bearing.

The combination is technically important because silicon nitride rolling elements provide electrical insulation between the bearing rings. SKF specifically identifies protection against electric-current damage as a characteristic of its hybrid bearings.

2RZ Non-Contact Seals

2RZ specifies sealing on both sides of the bearing.

For this exact reference, technical data identify the seals as non-contact NBR seals.

The integral sealing helps retain lubricant inside the bearing and restrict contamination from entering the rolling contact. SKF specifically states that integral sealing can extend bearing service life by keeping lubricant in and contaminants out.

The 2RZ construction must not be confused with an open 6007 or a metal-shielded 6007-2Z.

TN9 Cage

The suffix TN9 identifies the cage construction.

For SKF 6007-2RZTN9/HC5C3WT, TN9 denotes an injection-moulded, glass-fibre-reinforced polyamide 66 cage, rolling-element centred.

This is a non-metallic cage and is part of the exact bearing specification.

Consequently, a 6007 bearing with the same 35x62x14 mm dimensions but a different cage should not automatically be considered identical to SKF 6007-2RZTN9/HC5C3WT.

C3 Radial Internal Clearance

The C3 suffix specifies radial internal clearance greater than Normal. This is confirmed for the exact SKF 6007-2RZTN9/HC5C3WT configuration.

C3 is not a precision or quality class. It describes the initial radial internal clearance of the bearing.

This distinction matters because interference fits, temperature differences between the rings and operating conditions can reduce internal clearance after installation.

A hybrid 6007 bearing with Normal clearance should therefore not automatically be treated as the same configuration.

WT Grease

The WT suffix identifies the lubricant specification used in this bearing.

Technical data for the exact reference specify WT grease for a wide temperature range, with published catalogue information indicating -40°C to +160°C for the grease specification.

This temperature range describes the WT grease specification and should not automatically be interpreted as the permissible operating-temperature range of the complete bearing arrangement.

The actual permissible bearing operating temperature also depends on factors including load, speed, fits, surrounding components and thermal conditions.

Electrical Insulation

One of the key technical differences between SKF 6007-2RZTN9/HC5C3WT and an all-steel 6007 bearing is electrical behaviour.

SKF states that the bearing-grade silicon nitride rolling elements in hybrid bearings make the bearing electrically insulating and protect it against damage caused by electric current.

This characteristic is particularly relevant when bearing selection requires protection against current passage through the rolling contacts.

However, the product should not be assigned to a specific motor, generator or machine unless compatibility with that application has been verified separately.

Load Ratings and Operating Principle

For the exact SKF 6007-2RZTN9/HC5C3WT, current SKF-derived technical data specify:

C - Basic Dynamic Load Rating: 15.9 kN
C0 - Basic Static Load Rating: 10.2 kN.

As a single-row deep groove ball bearing, it is designed primarily for radial loading while its deep raceway geometry also enables it to accommodate axial loads in both directions.

The load ratings are engineering values used for bearing selection and life calculations. They should not be interpreted as universal maximum permissible loads for every installation.

Reference and Limiting Speeds

For SKF 6007-2RZTN9/HC5C3WT, SKF-derived product data specify:

Reference Speed: 26,000 r/min
Limiting Speed: 14,000 r/min.

These values apply to the exact sealed hybrid configuration and should not be replaced by speed ratings taken from a standard open 6007 bearing.

Actual permissible operating speed depends on load, temperature, bearing arrangement and other operating conditions.

Meaning of 6007-2RZTN9/HC5C3WT

The complete designation identifies a highly specific SKF configuration:

6007 - single-row deep groove ball bearing, 35x62x14 mm

2RZ - non-contact seals on both sides

TN9 - glass-fibre-reinforced polyamide 66 cage, rolling-element centred

HC5 - hybrid bearing construction with silicon nitride Si3N4 rolling elements

C3 - radial internal clearance greater than Normal

WT - wide-temperature grease specification.

For product identification, SEO and AI Search, the complete designation should always be retained:

SKF 6007-2RZTN9/HC5C3WT

Removing the suffixes would materially change the technical identification of the product.

SKF 6007-2RZTN9/HC5C3WT vs Standard 6007

The two bearings may share the same principal envelope dimensions of 35x62x14 mm, but they should not be treated as identical.

The exact SKF 6007-2RZTN9/HC5C3WT combines:

hybrid HC5 construction
Si3N4 ceramic balls
2RZ non-contact seals
TN9 polyamide cage
C3 internal clearance
WT grease

A standard 6007 bearing does not automatically have any of these additional specifications.

This distinction is particularly important for product-page anti-cannibalization: the page should focus on the hybrid HC5C3WT configuration, not merely on the generic 6007 size.

Selection and Interchangeability

When selecting an alternative for SKF 6007-2RZTN9/HC5C3WT, dimensions alone are insufficient.

The following should be compared:

• 35 mm bore diameter,
• 62 mm outside diameter,
• 14 mm width,
• single-row deep groove construction,
• hybrid bearing design,
• silicon nitride Si3N4 rolling elements,
• bearing-steel rings,
• non-contact seals on both sides,
• TN9 cage specification,
• C3 radial internal clearance,
• lubricant specification,
• dynamic and static load ratings,
• required operating speed,
• electrical insulation requirements.

A conventional all-steel 6007 35x62x14 should therefore not automatically be treated as a technically equivalent replacement.
