Technical calculations

Linear guide life calculations

Life
When linear guides operate in linear motion while supporting loads, repeated stresses apply on the rolling elements (balls) and raceways (rails), eventually causing scale-like flaking due to material fatigue. The total run distance until this flaking appears is defined as linear guide's "Life".
Rated life
Rated life is a total distance 90% of linear guides reach without flaking when a group of the same guides are run under the same condition. The rated life can be calculated with basic dynamic load rating and the load applied on the guides as follows.
When using linear guides, load calculations are initially needed. It is not easy to calculate the loads during linear motion due to vibrations and shocks, as well as load distribution on the guides. Furthermore, operating environment temperature has large effect on life. When these conditions are taken in consideration, the calculations would be as follows.
  • L: Rated life (km)
  • fH: Hardness factor (see Fig-1)
  • fT: Temperature factor (see Fig-2)
  • fC: Contact factor (see Table-1)
  • fW: Load factor (see Table-2)
  • C: Basic dynamic load rating (N)
  • P: Applicable load (N)
Hardness factor (fH)

In using linear guides, the shaft that balls contact must have sufficient hardness, If adequate hardness cannot be obtained, load rating decreases and life will be reduced as a result.
Please compensate the life value with the hardness factor.

Temperature factor (fT)

When the temperature of linear guides exceed 100℃, hardness of blocks and rails will be reduced, causing reduction of life. Please compensate the life rating with temperature factor.
* Please use linear guides within the resistant temperature range on product pages.

Contact factor (fC)

Table-1. Contact factor

Number of blocks installed on one rail and contact factor fC

1 1.00
2 0.81
3 0.72
4 0.66
5 0.61

In general, it is common to use 2 or more blocks on 1 rail. In such case, load applicable on each block would not be uniform due to machining variations. As the result, allowable load rating on each block would vary depending on the number of blocks used per rail. Please compensate the life rating with contact factor shown on Table-1.

Load factor (fW)

Table-2. Load factor

Application condition fw
No external shocks or vibrations and
speed is low 15m/min or less
1.0-1.5
No significant shocks or vibration and
med. speed 60m/min or less
1.5-20
External shocks and vibrations exist
and the speed is high 60m/min or over
2.0-3.5

When calculating loads applicable on linear guides, other than the weight of the object, inertial force due to motion speeds, moment loads, and variations of each over time must also be obtained accurately. However, accurate calculation would be difficult due to repeated starts and stops and various shocks and vibrations. Therefore, the Load Factors shown in Table-2 are used to simplify the life calculations.

Applicable load calculation method
When moment loads apply a block, use the following formula to convert the moment load to applicable load.
  • P: Applicable load (N)
  • F: Downward load (N)
  • C0: Static load rating (N)
  • MA: Allowable static moment - Pitching direction (N・m)
  • MC: Allowable static moment - Rolling direction (N・m)
  • Lp: Load point distance (m) in pitching direction
  • Lr: Load point distance (m) in rolling direction

IDEA NOTE Devising of ball plunger engaging position

The mating part of the ball plunger has the notches located slightly lower than the center of the parts height. Regardless of heat treating, when the notches are worn, this part can be turned upside down (use locating dowel pins, etc. to ensure the repeatability) to regain the initial condition.

IDEA NOTE Dual role pins

Locating pins are used to locate the linear guide rail, to prevent the block from falling off.

  • Example: electronic circuit components.
  • Size: W29 x D29 x H4.5mm

Design Specifications

Operating Conditions or Design Requirements

  • External dims: W220 x L495 x H210mm

Required Performance

  • Load: 8-10N (approx. 800g - 1kg)
  • Required force to move carriage: 16-18N (approx. 1.6 - 1.8kg) to initiate motion, after which only approx. 300g is needed to maintain motion.

  • Linear guide
    • Selected for its load bearing capacity and smooth guidance of linear motion.

Design Evaluation

Verification of main components

  • Calculation for ball plunger retaining force
    • One side of the V groove is 45 degrees, making plunger setting force and operating force the same.
    • The retaining force with plunger set for 0~0.1mm stroke (Almost zero-touch) is 8.1~10.1N
    • Max. load to overcome the V groove when set is 0.2mm, so 16~19N.

      ⇒ Select BPRM6 since required retaining force is within its load capacity.

Other Design Consideration

  • Adjust the pitch distance between notches on the carriage to control the positioning increments.
