6014Z NSK 70x110x20 Single-Row Deep Groove Ball Bearing

6014Z NSK is a single-row deep groove ball bearing with dimensions 70x110x20 mm. NSK identifies the reference 6014Z as a single-row radial ball bearing with a 70 mm bore, 110 mm outside diameter and 20 mm width. The suffix Z is technically important: it specifies a pressed-steel shield on one side only.

6014Z NSK - Product Characteristics

The 6014Z NSK belongs to the 60 series of single-row deep groove ball bearings. Its inner and outer rings have deep raceway grooves designed around the rolling balls. This geometry makes the bearing primarily suitable for radial loading while also allowing it to accommodate axial loads in both directions.

Unlike the open 6014 version, the 6014Z has a metal shield on one side. It must also be distinguished from 6014ZZ, where the double Z suffix identifies shields on both sides. NSK explicitly defines Z as a shield on one side and ZZ as shields on both sides.

Dimensions

The principal dimensions of 6014Z NSK are:

d - Bore Diameter: 70 mm
D - Outside Diameter: 110 mm
B - Bearing Width: 20 mm

Therefore, the commercial dimensional notation is:

70x110x20 mm

For this deep groove ball bearing, the third principal dimension is correctly identified as B, the bearing width. NSK's current bearing replacement documentation confirms the exact combination 6014Z - 70 mm - 110 mm - 20 mm.

Bearing Construction

6014Z NSK is a single-row deep groove ball bearing, also described in English technical terminology as a single-row radial ball bearing or single-row deep groove ball bearing.

The rolling elements are balls running in deep grooves formed in the inner and outer rings. The raceway geometry enables radial force transmission while also allowing axial loading in either direction. NSK specifically states that deep groove ball bearings can accommodate both radial loads and axial loads in both directions.

The defining construction feature of this exact version is the single pressed-steel shield indicated by the suffix Z. The shield provides additional protection for the internal bearing components and helps retain lubricant while avoiding the sealing characteristics of a contact rubber seal. NSK ranks sealing effectiveness from sealed bearings, through shielded bearings, to open bearings.

The opposite side of 6014Z is not shielded. This detail is essential when comparing it with 6014ZZ or sealed variants.

Loads and Operating Principle

For the NSK 6014 size, verified technical data give:

Basic Dynamic Load Rating Cr: 38,000 N
Basic Static Load Rating C0r: 31,000 N

These ratings correspond to approximately:

Cr: 38 kN
C0r: 31 kN

The deep-groove ball/raceway contact geometry means that 6014Z NSK primarily carries radial load but can also accommodate axial load in both directions.

The load ratings should not be interpreted as permissible operating loads without calculation. Actual bearing selection depends on load magnitude and direction, rotational speed, required life, fits, lubrication, internal clearance, temperature and operating conditions.

Meaning of the 6014Z NSK Designation

The designation 6014Z identifies the bearing configuration rather than only its dimensions.

6 - identifies the single-row deep groove ball bearing type.

0 - identifies the relevant dimension series within NSK's designation system.

14 - bore code. For bore codes 04 and above, NSK uses the code multiplied by 5 mm; therefore 14 x 5 mm = 70 mm bore diameter.

Z - pressed-steel shield on one side.

NSK's designation documentation explicitly differentiates:

6014 - open version
6014Z - one metal shield
6014ZZ - two metal shields

The suffix must therefore remain part of the product identification when selecting a replacement.

Selection and Interchangeability

A bearing from another manufacturer carrying a similar 6014Z designation may have the same principal dimensions, but dimensions alone do not establish complete technical interchangeability.

When selecting a replacement for 6014Z NSK, compare at least:

• bearing type and dimensional series,
• d = 70 mm,
• D = 110 mm,
• B = 20 mm,
• one-sided shield configuration,
• basic dynamic and static load ratings,
• radial internal clearance,
• tolerance/accuracy class,
• limiting speed,
• lubrication arrangement,
• cage design where relevant,
• required operating conditions.

Particular attention should be paid to the Z suffix. A 6014ZZ bearing is dimensionally similar but has shields on both sides and therefore is not the same construction as 6014Z.

Likewise, versions carrying additional suffixes such as clearance or precision designations should not automatically be treated as identical to the plain 6014Z NSK.

FAQ

What are the dimensions of 6014Z NSK?

The bearing has a 70 mm bore diameter, 110 mm outside diameter and 20 mm width, giving principal dimensions of 70x110x20 mm.

What type of bearing is 6014Z NSK?

It is a single-row deep groove ball bearing. NSK also classifies 6014Z within its single-row radial ball bearing range.

What does Z mean in 6014Z NSK?

The suffix Z means that the bearing has a pressed-steel shield on one side.

Is 6014Z the same as 6014ZZ?

No. 6014Z has one shield, whereas 6014ZZ has shields on both sides. The principal dimensions can be the same, but the closure configuration is different.

What loads can 6014Z NSK carry?

The deep-groove construction is primarily intended for radial loads and can also accommodate axial loads in both directions. The basic dynamic load rating Cr is 38 kN and the basic static load rating C0r is 31 kN.

Can I replace 6014Z NSK with another brand?

Do not determine interchangeability from the dimensions alone. Compare the exact bearing type, 70x110x20 mm dimensions, one-sided Z shield, load ratings, internal clearance, tolerance class, speed capability, lubrication and other operating requirements.

Does 6014Z have shields on both sides?

No. The exact NSK suffix Z denotes one metal shield. For shields on both sides, NSK uses the suffix ZZ.
