- 6. Feeler gauges 729865 series For accurate bearing clearance measurement SKF feeler gauges are designed to measure the internal clearance when adjusting spherical roller bearings. Two types are available, one with 13 blades of 100 mm (4 in) length and the other with 29 blades of 200 mm (8 in) length. High accuracy of measurement 729865 A is supplied with protective plastic cover 729865 B is supplied with protective steel cage Technical data Designation Blade length Blade thickness mm in mm in mm in mm in 729865 A 100 4.0 0,03 0.0012 0,08 0.0031 0,14 0.0055 0,04 0.0016 0,09 0.0035 0,15 0.0059 0,05 0.0020 0,10 0.0039 0,20 0.0079 0,06 0.0024 0,12 0.0047 0,30 0.0118 0,07 0.0028 729865 B 200 8.0 0,05 0.0020 0,18 0.0071 0,60 0.0236 0,09 0.0035 0,19 0.0075 0,65 0.0256 0,10 0.0039 0,20 0.0079 0,70 0.0276 0,11 0.0043 0,25 0.0098 0,75 0.0295 0,12 0.0047 0,30 0.0118 0,80 0.0315 0,13 0.0051 0,35 0.0138 0,85 0.0335 0,14 0.0055 0,40 0.0157 0,90 0.0354 0,15 0.0059 0,45 0.0177 0,95 0.0374 0,16 0.0063 0,50 0.0197 1,00 0.0394 0,17 0.0067 0,55 0.0216
- 7. Grease meter LAGM 1000E Accurate grease quantity measurement for adequate lubrication It is generally difficult to determine the correct quantity of grease when manually lubricating bearings, either using a grease gun or pump, which can result in either over- or under-greasing the bearing. That can negatively influence the bearing's service life and possibly result in machine breakdown. The SKF grease meter LAGM 1000E accurately measures grease discharge in volume or weight, in both metric (cm³ or g) and US units (US fl. oz or oz). It has a high maximum pressure of 70 MPa (10,000 psi), making it ideal for use in combination with many types of grease guns and pumps. Measures grease discharge in volume or weight, making conversion calculations unnecessary High accuracy facilitates adequate bearing lubrication, reducing the risk of over- or under-greasing Suitable for all SKF bearing greases of consistency classes up to NLGI 3 An oil and grease resistant rubber sleeve protects the electronics in case of impact The backlit LCD displays large and clear-to-read digits, including "low battery" indication Small, compact and lightweight design - only 0,3 kg (0.66 lb) Corrosion-free aluminium housing Easy to install and use Technical data
