1 Put on your thinking caps! Which bearing would you use on your FIRST robot?: plastic, metal or bronzeWhy did you choose that particular bearing?Which type of bearing would you choose to use on a lawn mower or farming equipment?Which type of bearing would you choose to use on an outboard, high-speed boat motor?Remember your answers … you might be surprised!

6 Remember your answers?Which bearing would you use on your FIRST robot?: plastic, metal or bronzeWhy did you choose that particular bearing?Which type of bearing would you choose to use on a lawn mower or farming equipment?Which type of bearing would you choose to use on an outboard, high-speed boat motor?
7 Tidbits about bronze bearings DisadvantagesVery sensitive to dirtSensitive to edge pressureHigh temps breaks down oilLow chemical resistanceNot suitable for linear movementsSensitive to impacts and oscillationsAdvantagesVery low coefficient of friction possibleHigh precisionHigh rotational speeds possible (1,200 SFM)High PxV value possible (50,000 PV)
8 Tidbits about plastic bearings AdvantagesLightweightNo lubrication neededMaintenance-freeDry-runningVibration-dampeningDirt- and dust-resistantCorrision-resistantDisadvantagesSensitive to extreme temperatureSensitive to extremely high loadsSensitive to extremely high, constant speeds
9 Plastic vs. Bronze Iglide® Oilite Bronze Max PSI: up to 21,750 PSI 8,000 PSIMotion: Any (including dual) HS rotatingShafting: Any (soft/SS/HR/steel) Carbon steel, hardGrades available: OverDirty environments: Yes NoResists squeaking: Yes Only if it’s oiledEdge loading: Yes NoUnderwater: Yes NoSuitable for clean rooms: Yes NoPlastic Contact Yes NoService life predictors: Yes ?Technical data available: Yes ?
10 Edge pressure F metal bearings plastic bearings The bearing material has a low flexibility:the contact surface between shaft andbearing is only a point.High specific pressure (load per mm²)High wear of the bearingShaft could be consumedThe bearing material has a high flexibility:the contact surface between shaft andbearing is a bigger surfaceLower specific pressure (load per mm²)Lower wear of the bearingShaft will be not consumed!
11 A closer look at iglide plastic bearings Features:Long-lastingSelf-lubricatingMaintenance-freeDust- and dirt-resistantMore than 7,000 metric and inch bearing sizes and styles from stock
12 In the real world Benefits of iglide J Iglide J on lawn mower deck Enables pivoting and linear movement in caster wheelPlastic bearings outperformed bronze in every testBenefits of iglide JWithstands high edge pressureWithstands high impact/shock loadsCompensates for edge loadsGreat wear resistance with high loadsNo grease, no maintenanceCorrosion-resistant
13 In the real world Mercury Marine Iglide G300/D on outdoor, high-speed boat motorIglide D enables tilt and trim of the motor in the steering mechanism and transform assemblyIglide G300 is used in oscillating pivot jointsBenefits of iglide JEliminates the need for grease, which contaminates water and potentially harms wildlifeEliminates maintenanceLow water absorptionLow coefficient of frictionCorrosion-freeIn depth test data and predictability methods
15 In the FIRST arena Carmel High School, Team 868 Products used Used on: Iglide bearingsIgubal® spherical bearingsUsed on:Shooting systemRoller systemBenefits:LightweightReduced weight of the robot by 20 pounds!Iglide (inside wheel mechanism)
16 A closer look at igubal spherical bearings FeaturesSelf-aligningOil-freeIncludes spherical, clip, pillow block and rod end bearings
17 In the real world Benefits of iglide J Big Cat Human Powered Vehicles Igubal spherical bearings on a recumbent tricycleEnables lighter, cleaner and more reliable steering for the riderBenefits of iglide JSelf-aligning, which diverts the need for exact placement of shafts/housingLubrication-freeCorrosion- and wear-resistant80% lighter than steelExcellent vibration-dampeningigubal rod end
18 “The igubal bearings do a better job of absorbing vibration from wheel to arms. We also can use a really large rod end without increasing the weight too much. This in turn enables us to use a stiffer rod which produces better wheel alignment.”~Paulo Camasmie, president of Big Cat Human Powered Vehicles
19 In the FIRST arena Upper Darby High School, Team #357 Products used 34 igubal spherical bearings253 iglide Z bearingsDryLin S aluminum shaftingUsed on:Shooting systemRoller systemBenefits:LightweightSelf-aligningMaintenance-free, which saved the team a lot of time!
21 A closer look at DryLin R linear bearings Features:Corrosion-resistantDirt-resistantVibration dampeningIdeal alternative to re-circulating ball bearings
22 In the real world Benefits of DryLin R International Climbing Machines DryLin R on a climbing machineAids machine in scaling walls to eliminate hazardous chemicals from various locations such as bridges, ships and towersBenefits of DryLin RDurableLightweight, which makes it much easier for the machine to easily adhere to surfaces
