Japanese Only

Yuei Caster PM series

Long life with improved durability. Running cost greatly decreased.

  • Fully prevents resonance during towing. Decreased load on the turning portion, dramatically reducing tread abrasion.
  • Adopted new material (high tensile steel) to further improve durability. Long life reduces cost.

Development Secrets

Reason For Development

The PM series are high performance industrial use casters that are strong, turn easily, have light deadweight, and have reduced noise. This was developed with the concept of targeting a higher end compatible product with the conventionally sold J series, which are general industrial use casters. This also suppresses increases in costs.
Firstly, the reasons leading to development of a higher-end compatible product for industrial use casters are as follows. Industrial use casters used for factory carts, etc., are consumable goods. There is an aspect of emphasizing cost over performance, and the J series sufficiently met a specific performance standard.
But this series only met that specific standard, and had much room for improvement when considering the needs of the customers using the product with regards to durability, operability, noise, etc. Conventional products on the market include many casters with the described performance level, but these were not very cost-efficient. Then we wondered whether we could make industrial use casters that maintain the same cost and provide the kind of performance that will satisfy customers, and set out to develop the PM series.

Challenges Along The Way And Encountering New Materials

We started PM series development with solid goals, but development was hardly smooth, and we did encounter problems. As you would expect from what you have read above, the performance and costs were difficult to balance. We went through many shape concepts and recalculations.
We arrived at using high-strength material, like an automobile body that uses high tensile steel. Using this material enables attaining higher strength than the conventional product, even though the plate thickness is thinner than the conventional product. This allowed us to balance the cost and lighten the dead weight. We are very satisfied with finding an ideal material. But the press processing method differed from the conventional product when the new material was adopted, and we had some difficulty with processing it to the dimensional accuracy required for functioning as a caster. We thoroughly evaluated every possible factor and went through a trial-and-error process.

Discovery Of New Added Value

By repeating the trial-and-error process, not only did we attain the performance initially intended, but we also additionally succeeded at reducing resonance occurrence. Resonance refers to caster vibrations that occur during high speed travel. Resonance occurrence applies excess load to the casters and leads to early damage. The combination of preventing resonance and the aforementioned more durable new material resulted in the creation of a caster with long service life. Additionally, resonance occurrence leads to noise. By preventing resonance from occurring, noise was also reduced. We succeeded at reducing resonance occurrence by developing a new structure for the turning portion, with a proprietary pathway for steel balls serving as bearings. This was made with precision, eliminating the unsteadiness of conventional products and enabling maintaining like new superior operability for a long time.

The PM Series Casters

In addition to meeting the initially mentioned product concept of being strong, turning easily, having light dead weight, and having reduced noise, the PM series also became casters with very long service life. Long service life means proportionately decreased costs of repurchasing and replacing, which in turn reduces the running cost for customers. We were very pleased with this, because development of the PM series started with wanting to leave the costs the same while creating industrial use casters with performance that satisfies our customers. Our customers will be happier with reduced costs compared to costs remaining the same.

Praise From Our Customers

Though this differs by the customer usage environment, we have received comments from happy customers saying that the service life nearly tripled. Customers using this for towing are also giving us good reports. We urge you to give these a try.
