In the rotary power transmission world, timing pulleys<\/a> and timing belts<\/a> are king!\u00a0 There are a variety of profiles, widths, material, and lengths to choose from.\u00a0 Depending on your application needs, choosing the right profile is key.\u00a0 There are many factors to consider in choosing the right profile.\u00a0 Check out our 4 part YouTube series on timing pulleys and belts!<\/a>\u00a0 In this post, we will be comparing 2 profiles that MISUMI<\/a> provides and supports, MR and GT.<\/p>\n

What is the difference between MR and GT?<\/p>\n

To narrow it down on a particular profile, we will be highlighting and clearing up many misconceptions of our newest addition to the power transmission profile, MR.\u00a0 MR is a curvilinear profile and is compatible with PowerGrip\u00ae GT\u00ae 3 from Gates.\u00a0 MR is GT\u00ae and vice versa GT\u00ae is MR.\u00a0 What about MISUMI\u2019s 2GT, 3GT, and 5GT? Yes, let\u2019s go into the history of this profile.<\/p>\n

MISUMI<\/a>\u2019s 2GT<\/a>, 3GT<\/a>, and 5GT<\/a> originated in Asia as a circular profile and naturally, as a subsidiary of MISUMI the US location adopted it.\u00a0 They are very similar to PowerGrip\u00ae GT\u00ae from Gates in terms of performance, except for the shape.\u00a0 We wanted to expand our product offering and provide even more for our customers so we adopted MR as the nomenclature for our line of timing belts and pulleys compatible with Gates, GT\u00ae. \u00a0We have them available in the 2mm<\/a>, 3mm<\/a>, 5mm<\/a>, 8mm<\/a> and 14mm<\/a> pitches.<\/p>\n

Is there a difference in performance?<\/p>\n

This all depends on your application of course but both profiles perform well as there is very minimal backlash.\u00a0 MR will provide in high load applications, accuracy, and resist ratcheting.\u00a0 The curvilinear profile will provide more surface contact between the pulley and belt.\u00a0 The more surface contact between the pulley and belt, the longer the life of the belt and greater prevention of tooth distortion.<\/p>\n

Here is a comparison of the MXL profile vs. the 2GT profile backlash.<\/p>\n

\"\"<\/p>\n

What is backlash?<\/p>\n

Backlash is recoil between mechanical parts.\u00a0 This is something to avoid especially in accuracy applications.\u00a0 The more surface contact the less backlash, hence, with the 2GT\/MR is the better profile.<\/p>\n

Here is a chart comparison of different tooth profiles.\u00a0 As you can see, MR\/GT Power Grip is curvilinear profile.\u00a0 2,3,5GT MISUMI<\/a> is a circular profile.\u00a0 MISUMI USA<\/a> has a variety of profiles to choose from and of course, the configurability options for bore, material, number of teeth and even shaft installation.<\/p>\n

\"\"<\/p>\n

Here is a comparison of MR vs. HTD<\/p>\n

\"\"<\/p>\n

As you can see, the MR has more surface contact comparted to HTD.<\/p>\n

We hope this clears up things about MR and GT.\u00a0 If you have any further questions, please contact our Power Transmission Engineering Team at engineering@misumiusa.com<\/a>.\u00a0 Let us help you size the right belt and pulley for your transmission application, we have the power!\u00a0 If you missed last week\u2019s post regarding LTBC (Low Temperature Black Chrome) plating, check it out here!\u00a0 You\u2019ve got the power!<\/p>\n
