Products Description
The 10mm linear rod, as the core guiding component of linear motion systems, plays a key role in automated equipment, precision instruments and other fields by virtue of its precise specification parameters and compact structural design. Such linear rods are usually combined with sliders, linear bearings or optical shaft components to form a linkage mechanism. Through surface treatment with low friction coefficient and geometric accuracy control, they achieve smooth and stable linear reciprocating motion.
Its 10mm diameter specification is particularly suitable for two typical scenarios: one is the environment with strict requirements for motion accuracy, such as the wafer transfer platform of semiconductor equipment and the guide rail system of medical imaging equipment, which can ensure micron-level positioning accuracy; the other is the compact mechanical structures with limited space, such as the joints of small robots and the micro-modules on 3C product production lines, which can realize efficient guiding functions within the limited installation space.

1. Product Features of 10mm Linear Rod
Precise Guiding Performance
The 10mm linear rod is manufactured with tight dimensional tolerance (≤0.01mm) and excellent straightness accuracy, ensuring stable linear motion without deviation even at high speeds.
When paired with precision linear bearings, it achieves exceptionally smooth sliding performance with radial runout ≤0.03mm, making it ideal for CNC, automation, and 3D printing applications.
Low-Friction Design
When matched with linear bearings, the friction coefficient is reduced by up to 40%, supporting high-frequency reciprocating motion up to 200 cycles per minute.
Its wear rate is only one-fifth that of traditional bushing systems, greatly extending service life and maintaining consistent performance under continuous operation.

When the shaft length exceeds 1m, intermediate support structures (spacing ≤1m) should be added to avoid deflection deformation due to self-weight. |
|
Maximum Load |
Radial load: static 300N / dynamic 150N |
In dynamic conditions, the load coefficient should be corrected according to the operating speed (v ≤1.5m/s) to prevent overload from affecting service life. |
|
Surface Treatment |
Hard chromium plating (conventional wear resistance), nitriding treatment (high hardness), stainless steel material (corrosion resistance) |
In humid, acid-base and other corrosive environments, stainless steel materials or nitriding treatment are preferred to enhance protection performance. |

Structure and Characteristics of 10mm Linear Rod
Cylindrical Shaft and Raceway Design
Both the shaft and the ball raceways are precisely machined into a cylindrical shape.
The load-carrying balls are axially aligned and guided by a precision cage, ensuring smooth and stable linear motion.
The outer sleeve, made from high-carbon chromium bearing steel, undergoes heat treatment and precision grinding to achieve high surface hardness and wear resistance.
Excellent Interchangeability
Thanks to the standardization of dimensional tolerances for each component, DLY linear bearings offer full interchangeability.
The shaft is finished using precision external grinding, enabling highly accurate assembly tolerances and ensuring compatibility with standard linear motion systems.
High-Hardness Outer Ring
The outer ring is manufactured from high-strength bearing steel and hardened throughout its structure.
This design allows needle roller bearings or linear ball bearings to be directly embedded into the circumferential surface, maintaining rigidity and extending service life.
High-Precision Cage Design
The integrated cage holds 4 to 6 rows of steel balls, precisely guiding them in the direction of motion to achieve consistent and stable positioning accuracy.
For small-diameter bearings, a single-piece synthetic resin cage is used-providing low-noise operation, smooth movement, and excellent lubrication performance.
LM Box-Equipped Units (SC Type)
The SC-type linear bearing block features an LM-type bearing installed inside a compact and lightweight aluminum housing.
It can be easily fixed to the worktable with bolts for quick assembly.
Multiple rows of balls inside the housing ensure that at least two rows are always in contact with the load, improving stability and extending service life.
Fit and Installation
Typically, the bearing seat adopts a clearance fit for ease of installation.
When higher rigidity or minimal clearance is required, an interference fit can be applied.
This flexibility allows engineers to select the most appropriate fitting method based on load and precision requirements.
