Technical calculations
■Life of Linear Bushing
When the linear systems are in motion with loads, rolling surfaces and races are subject to repeated stress and will show scale-flaking due to material fatigue. The total run distance until the flaking appear is the "Life" .
The rated life can be calculated with the following formula based on basic dynamic load rating and the load applied on the bushing.
- L: Rated life (km)
- fH: Hardness factor (See Fig.1)
- fT: Temperature factor (See Fig. 2)
- fC: Contact factor (See Table-3)
- fW: Load factor (See table-4)
- C: Basic dynamic load rating (N)
- P: Applicable load (N)
Hardness factor (fH)
For linear systems, the shaft that the balls contact must have sufficient hardness,If the shaft does not have sufficient hardness, the load rating decreases and life will be reduced as a result.
Fig.-1. Hardness factor
Temperature factor (fT)
When the temperature of linear systems exceed 100℃, hardness will be reduced and as a result, the allowable loads and life will be reduced.
Fig.-2. Temperature factor
Contact factor (fC)
In general, it is common to use 2 linear systems are used for 1 shaft, in general. In these cases, the load on each linear system will vary depending on machining accuracies and will not have equally distributed loads. As a result, the allowable load per linear system will very depending on the number of linear systems used on one shaft.
Table-3. Contact factor
| Number of bearings installed on one shaft. | Contact factor fC | |
|---|---|---|
| 1 | 1 | |
| 2 | 0.81 | |
| 3 | 0.72 | |
| 4 | 0.66 | |
| 5 | 0.61 | |
Load factor (fW)
To calculate load applied to the linear system, in addition to object weight, inertia force attributed to motion velocity, moment loads and variations of each over time must be obtained. However, for reciprocating motion applications, it is difficult to obtain accurate calculations due to the effects of vibrations and shocks. Therefor, use Table-2 below in order to simplify the Life Calculations.
| Application conditions | 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 | 1.5～2.0 |
| External shocks and vibrations exist and the speed is high 60m/min or over | 2.0～3.5 |
Life in hours can be obtained by calculating travel distance per hour. When stroke length and stroke cycles are fixed, see the equation below.
- Lh: Life (Hr)
- L: Rated life (km)
- Ls: Stroke length (m)
- n1: Number of cycles per minute (cpm)

- Tray
- External dims.: W180 x D200 x H179
- Weight: 0.6kg
- Max. weight
(5 workpieces + 5 Trays)
(0.3 x 5) + (0.6 x 5) = 4.5kg
Design Specifications
Operating Conditions or Design Requirements
- Slide stroke: 116mm (Pitch 29mm x 4)
- External dims.: W480 x D350 x H537

- Motor
- Load retaining type is selected to prevent falling due to own weight.
- Linear motion gearhead
- Vertical motion type is selected to move the workpieces up/down.
- Sensor
- 2 output type sensor is selected for pitch feeding.
Design Evaluation
Verification of main components
- Verify the motor regarding required speed and load capacity.
- Rack speed
- Motor speed (Ns): 90~1600 r/min
- Reduction ratio of linear motion gearhead (i): 35.36
- Pitch circle DIA. of the pinion (Dp): 12mm
- Rack speed (V)
V = Ns × (1 / 60) × (1 / i) × π × Dp - Vmin = 90 × (1 / 60) × (1 / 35.36) × π × 12 = 1.6 mm/s
- Vmax = 1600 × (1 / 60) × (1 / 35.36) × π × 12 = 28.43 mm/s
- Assumed rack speed: 15mm/s, OK.
- Max. payload
- Motor torque Tm: 45N・m
- Reduction ratio of linear motion gearhead (i): 35.36
- Pitch circle DIA. of the pinion (Dp): 12mm
- Transmission efficiency by reduction ratio (η1) : 0.66
- Transmission efficiency of rack and pinion (η2): 0.9
- The maximum allowable load capacity (W):
W = Tm × I × η1 / (Dp / 2) × η2 / 9.8 = 45 × 35.36 × 0.66 / (12 / 2) × 0.9 / 9.8 = 16 kg
Total elevating mass: Workpiece + Tray + Base + Rack + Others = 4.5 + 1.3 + 1 + 2 ＝ 8.8 kg ＜ 16 kg
Other Design Consideration
- Pitch feeding is possible when using a photomicro sensor to detect the pitch.
- The lower most tray and the upper most tray are detected by a photoelectric switch.
- For detecting the lower most limit, another sensor and pitch detection plate are placed (Limit switch).
- For detecting the upper most limit, another sensor and a sensor flag are placed (Limit switch)
