Ball Splines Round Flanged

1. Spline Shaft rolls along the spherical groove using the steel ball inside the spline nut, allowing even a single-axis mechanism to perform linear motion while keeping the nut undeviated in the rotation direction.
2. Compared to the combination of guide shaft and linear bushing, Spline Shaft enables linear motion with high sensitivity and high precision, and can withstand higher loads.
3. Spline Shaft can safely transmit torque even under cantilever load and deliver high durability.

1. Spline Shaft Shipping within 5 days after placing an order.
2. Drawing-based machining is no longer required, saving the time for design.
3. Spline Shaft length can be specified in 1mm increments.
4. Various alterations are available to meet different usage scenarios.
5. This product of Spline Shaft has a lower price compared to the MISUMI standard products (produced in Japan) and better performance compared to generic products on the market.

■Precautions for Selection and Use of Spline Shaft
1. The relative positions of the grooves of Spline Shaft, the keyways and oil holes of straight nuts, and all the alterations (wrench flat, set screw flat, etc.) in the 3D model are for reference only and may differ from their actualpositions.
2. When re-inserting a nut into the Spline Shaft, be sure to insert it horizontally, otherwise the ball will fall off.
3. As resin parts are used inside the nuts, please use them at temperatures below 80℃.
4. Although the nuts are greased on the inside before leaving the factory, please re-grease them every 2~3 months or every 50km of traveling distance after receipt of the goods, otherwise their use will be impaired.
5. No guarantee is given for the noise level of this product.
6. No guarantee is given that the Spline Shaft or nuts of this product will fall freely.
7. This product is a machined type, so there will be knife patterns and color difference in its appearance. It is normal for the product to have some scratches or color changes. Please feel free to use.
8. The Spline Shaft is quenched, and annealed during machining.
  Due to the annealing treatment, the hardness of the machined part + area about 15 mm before and after the part may be reduced (see the following example). And the annealed section is out of the guaranteed range of outerdiameter dimensional tolerance.
  Subtract the size of the annealed section when calculating the stroke.

Since its establishment in 1963 in Japan, MISUMI Group Inc. has been providing customers with a wide range of high quality parts such as FA factory automation parts, mold parts, electronic parts, tools and consumables in a fast andaccurate manner. We have created a low-cost business model by compiling our own catalogs and establishing a marketing system to sell our products directly, and we continue to develop MISUMI branded products with a high level of quality bydeveloping an annual product plan based on customer feedback and requests. MISUMI established MISUMI Precision Machinery Co., Ltd. in China in June 2003, and then changed its name to MISUMI (China) Precision Machinery Trading Co., Ltd. inJune 2007, with its headquarters in Shanghai. Since the beginning of the stamping die standard parts business, the businesses of FA standard parts, plastic die standard parts and machining tools have been officially started successively,and the rapid development of MISUMI in China has won the full support of customers. China's manufacturing industry has unlimited prospects, which is why China's manufacturing industry market has become one of the most competitiveindustries in the world. Thus was born MISUMI's business philosophy - the key to the future of manufacturing in China is cost competitiveness as well as "quality" and "time".
