<\/i><\/i><\/span>Q: Are dimensions compatible as other manufacturers?<\/span><\/a><\/h4><\/div>
\n

A: In most cases, the rail and block mounting dimensions are the same. Block size might have slight differences. Please verify both our compatible chart and other manufacturer\u2019s catalogue for more detail information.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Can we replace your linear guide block or ball screw nut on other manufacturer\u2019s rail or screw shaft? Vice versa.<\/span><\/a><\/h4><\/div>
\n

A: Yes can be added or replaced with Interchangeable Linear Guides. For example at normal precision, LDH series linear guides are interchangeable to HIWIN’s HG series linear guides, ball screws are interchangeable to TBI\u2019s products.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: How to understand non-interchangeable products?<\/span><\/a><\/h4><\/div>
\n

A: All non-interchangeable types of linear guides and ball screws are sold as a set, with blocks mounted on rail or nuts mounted on screw shaft, and precision standard is only guaranteed for original purchased set.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: What are the standard colors of the block (slider or carriage)?<\/span><\/a><\/h4><\/div>
\n

A: For LDH standard series, black and red; For SG series, blue and black.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Which linear guide is suitable for the food and medical industry?<\/span><\/a><\/h4><\/div>
\n

A: We can provide miniature linear guide made of stainless steel.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Can the nut be purchased separately and installed on the existing screw?<\/span><\/a><\/h4><\/div>
\n

A: No. The nut and the screw need to be adjusted before they can be paired. The requirements for preload and clearance are achieved by adjusting the steel balls.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Why is the precision standard on the drawing different from the JIS standard?<\/span><\/a><\/h4><\/div>
\n

A: JIS grade accuracy for example C3, C5, C7, C3=0.008, C5=0.018, C7=0.05 (mm)
\nOur factory accuracy grade for example P2, P3, P4, P2=0.008, P3=0.012,, P4=0.016, P5=0.02 (mm)
\n**P3 accuracy means the positioning error of any 300mm effective stroke is \u00b10.012mm<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: How many turns can be offered?<\/span><\/a><\/h4><\/div>
\n

A: The standard number of turns for a C7 rolled ball screw is T4 and T8. C3, C5 grinding ball screw turns can be customized<\/p><\/blockquote>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Do you provide double seals or scrapers like design of DD and ZZ seals?<\/span><\/a><\/h4><\/div>
\n

A: Yes both metal and plastic material available<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Do linear guides have to be re-lubricated?<\/span><\/a><\/h4><\/div>
\n

A: Re-lubrication is not necessary, as we will apply lubricating oil before the products leave the factory.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: What are the packaging standards for air and sea transportation?<\/span><\/a><\/h4><\/div>
\n

A: In order to protect the goods from bumps, we provide fumigation-free Laminated Veneer Lumber packaging.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: How do you make sure ball will not fall out during transportation?<\/span><\/a><\/h4><\/div>
\n

A: Plastic rails are mounted on block (carriage).<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: In some special environments, such as high corrosion and high salinity working environment, can the linear guide work normally?<\/span><\/a><\/h4><\/div>
\n

A: We provide blackening surface treatment.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: How to inspect the precision of the ground ball screw?<\/span><\/a><\/h4><\/div>
\n

A: We have a laser detector to test the accuracy of the ball screw, and a test report can be issued with an accuracy of \u22640.012 mm<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: The relationship between the Length-to-Diameter ratio and accuracy of the ground ball screw.<\/span><\/a><\/h4><\/div>
\n

A: Please refer to table in ball screw detail page.<\/p><\/blockquote>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Q: Can ACME screw be provided?<\/span><\/a><\/h4><\/div>
\n

A: Yes. ACME screw is made of 45# steel or stainless steel. The surface treatment is black chrome plating at low temperature, and the accuracy level can reach 7E\/7H.<\/p><\/blockquote>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>
